Political lobbying is the attempt by individuals, businesses, charities and other special interest groups to influence government decision-making. This can include shaping the content of new legislation, altering government policy or securing public contracts.

While lobbying is a standard and often legitimate part of a democratic society – allowing stakeholders to present their views to policymakers – it is persistently controversial. Debates surrounding lobbying in the UK focus on concerns about transparency, the risk of “cash for access” and the potential for wealthy or powerful interests to exert undue influence on the political process.

Lobbying derives its name from the lobbies or hallways of parliament where MPs and peers gather before debates and votes.

In recent years, a series of high-profile scandals have led to significant changes in the rules governing the conduct of lobbyists, MPs, and former ministers.

Lobbying techniques

The best-known and most straightforward lobbying tactic involves direct engagement with ministers, their special advisers, civil servants and other MPs. This “direct lobbying” can take the form of formal meetings, but also includes networking at party conferences, attendance at social events, the construction of cross-party groups and encounters through informal contacts.

Lobbying firms, which may be employed by a third party interested in a particular policy, frequently market themselves on the basis of their contacts and knowledge base. The Hansard Society has estimated that MPs are approached over 100 times a week by professional lobbyists.

More indirectly, lobbyists also seek to influence the wider political environment. They may attempt to frame a debate by developing language and arguments to make a particular policy goal seem more attractive and palatable. For example, a campaign might focus on the “economic benefits” of a project to distract from its potential environmental harms, or frame a new technology as “climate-friendly” to minimise other possible social harms.

The regulation of lobbying

The regulation of lobbying in the UK is a patchwork of legislation and codes of conduct, each addressing a different aspect of the issue.

The Labour Party’s manifesto for the 2024 general election included a pledge to “review and update post-government employment rules to end flagrant abuses seen under the Conservatives.”

The party added: “This includes enforcing restrictions on ministers lobbying for the companies they used to regulate, with meaningful sanctions for breaching the rules.”

A lobbyists register

The Transparency of Lobbying, Non-Party Campaigning and Trade Union Administration Act 2014 established a statutory register of consultant lobbyists. The register of consultant lobbyists is managed and maintained by the Office of the Registrar of Consultant Lobbyists (ORCL).

The register provides information about consultant lobbyists and their clients. Consultant lobbyists have a statutory duty to register.

However, the register has been criticised for its narrow scope. It does not cover a vast amount of lobbying activity. A 2024 report by the Chartered Institute of Public Relations (CIPR), which represents public relations professionals (lobbyists), identified six key exemptions within the act. They are:

1. Non-registerable communications
2. VAT exemption
3. No payment for communications
4. Incidental lobbying exemption
5. Employee status exemption
6. Representative organisation exemption

The CIPR states: “It is not so much the case that the Lobbying Act contains loopholes. Rather, its exemptions provide an expansive and open door to those seeking to avoid registration.”

From the founding of the ORCL to the publication of the report in 2024, 96% of investigations into suspected unregistered consultant lobbying yielded that there was no requirement for the communication in question to be registered. The CIPR describes the act as “fundamentally inadequate”.

The Foreign Influence Registration Scheme (FIRS)

The Foreign Influence Registration Scheme (FIRS), introduced under the National Security Act 2023, requires any individual or entity that has an arrangement to carry out political influence activities in the UK at the direction of a foreign power to register these activities. The FIRS came into force on 1 July 2025.

The scheme is designed to provide greater transparency about the scale and nature of foreign state lobbying in the UK.

The rules for MPs

The conduct of MPs is governed by the House of Commons code of conduct. Following the Owen Paterson affair in 2021, a high-profile lobbying scandal, the rules were tightened significantly.

MPs are now explicitly prohibited from accepting any paid work to provide services as a “parliamentary strategist, adviser or consultant.” This rule, contained in a revised code of conduct, was approved by the House of Commons on 12 December 2022. It followed a recommendation by the committee on standards in public life.

It is also a longstanding requirement that MPs must declare all outside financial interests in the public Register of Members’ Financial Interests.

The rules for former ministers

Under the ministerial code, those who have served in government must “not profit improperly” from their experience, nor should their future employers “gain any unfair advantage through privileged access to government.”

Under the code, for two years after leaving office, former ministers must abide by the business appointment rules and seek advice from the independent adviser on ministerial standards about any appointments or employment they wish to take up.

If a former minister is found to have seriously breached the business appointment rules they will be expected to repay their full severance payment.

Rules for all-party parliamentary groups (APPGs)

All-party parliamentary groups (APPGs) are informal, cross-party interest groups of MPs and peers who share a common interest in a particular policy area, country or subject. In recent years, they have been the subject of controversy regarding their funding, transparency and potential to be used as vehicles for improper lobbying and foreign influence.

Concerns over the operation of APPGs grew significantly in the early 2020s. A 2021 BBC News report cited concerns that APPGs were being used as a “back door” for commercial lobbying and for influence by foreign states. Concerns led to a major review by the House of Commons committee on standards.

In response to the committee’s final report, a series of major rule changes were all implemented in March 2024 to tighten regulations. The rules therefore applied from the beginning of the parliament elected in July 2024.

Under these rules, APPGs are now prohibited from receiving any funding or benefits in kind from foreign governments.

Parliamentary access passes

One particularly controversial feature of the debate around lobbying in the United Kingdom surrounds the issue of parliamentary access passes.

Former MPs are forbidden from using their pass in order to use the House’s dining facilities for lobbying activities. However, critics have long argued that the system is open to abuse. It is a well-known practice for lobbyists to hire ex-MPs and ex-ministers in the course of lobbying work.

What is perhaps less well known is that ex-MPs have the right to apply for parliamentary access passes. This pass grants the former MP easy access to the Palace of Westminster, including access to its restaurants and bars.

For those who become subsequently engaged in lobbying, these passes are helpful for engaging former colleagues.

In September 2020, a request by the Guardian under the Freedom of Information Act found that 324 former MPs had used their parliamentary passes in a single year, with one doing so on as many as 82 occasions within a calendar year.

The Guardian‘s investigation found that Stewart Jackson, the Conservative MP for Peterborough from 2005 to 2017, used his access pass “82 times in the year from July 2018 to June 2019 – almost one in every two days on which parliament sat in that period.” Jackson’s LinkedIn profile at the time stated that he was working as a lobbyist.

Jackson did not respond to the Guardian‘s attempts to contact him.

Ivor Caplin, the Labour MP for Hove from 1997 to 2005, was another regular attendee, according to the Guardian‘s investigation. The former MP was the founder of Ivor Caplin Consultancy.

Caplin denied having “used the House for the purposes of my business.”

In November 2021, the House of Commons speaker, Lindsay Hoyle, signalled his opposition to the practice.

He told the commons: “If you’re a lobbyist, I don’t think it’s right they should have a pass for this House. Absolutely not.”

Lobby scandals: Cameron’s pledge and the Greensill affair

On 8 February 2010, Conservative Party leader David Cameron delivered a speech in which he identified lobbying as poised to become the next major public scandal.

Cameron was elected as leader of the Conservative Party in December 2005 on a platform of “modernisation”. Speaking in London mere weeks before the 2010 general election, Cameron sought to position the Conservative Party as a reforming force.

The address, entitled “Rebuilding trust in politics”, was also styled as a response to the 2009 expenses scandal. The shocking revelations as to the widespread misuse of parliamentary allowances by MPs had severely damaged the reputation of Westminster.

In his speech, Cameron described a shadowy system of “lunches, the hospitality, the quiet word in your ear” which allowed big business, represented “ex-ministers and ex-advisers for hire”, to secure access to government officials.

Cameron stated: “It is the next big scandal waiting to happen. It’s an issue that crosses party lines and has tainted our politics for too long, an issue that exposes the far-too-cosy relationship between politics, government, business and money.”

He added: “We believe in market economics, not crony capitalism. So we must be the party that sorts all this out.”

Cameron pledged that a future Conservative government would introduce a statutory register of lobbyists to force disclosure of who was lobbying whom.

The 2010 general election resulted in the country’s first hung parliament since February 1974, ending 13 years of Labour government. Cameron was appointed prime minister of a Conservative-Liberal Democrat coalition government.

The 2010 coalition agreement stated: “We will regulate lobbying through introducing a statutory register of lobbyists and ensuring greater transparency.”

Cameron’s moderniser moralising was widely recalled more than a decade later during the controversy surrounding his own lobbying activities for the finance firm Greensill Capital.

Having departed Downing Street, Cameron’s work for Greensill included messaging the then chancellor, Rishi Sunak, and other senior government figures. He was reported to have texted Sunak’s private phone asking him to give Greensill special access to hundreds of thousands of pounds of emergency Covid loans during the height of the coronavirus crisis.

As a result, Cameron found himself under investigation by the Registrar of Consultant Lobbyists, a body created under the Lobbying, Non-Party Campaigning and Trade Union Administration Act 2014. This landmark lobbying legislation was passed during Cameron’s tenure as prime minister.

The watchdog ultimately concluded that Cameron’s activities did “not fall within the criteria that require registration on the Register of Consultant Lobbyists”.

The House of Commons Treasury select committee concluded that while Cameron’s actions did not break the rules, they showed a “significant lack of judgement”.

The committee reported: “Mr Cameron’s use of less formal means to lobby government showed a significant lack of judgement, especially given that his ability to use an informal approach was aided by his previous position of prime minister…

“We accept that Mr Cameron did not break the rules governing lobbying by former ministers, but that reflects on the insufficient strength of the rules, and there is a strong case for strengthening them.”

Lobbying scandals: the Owen Paterson affair

On 26 October 2021, the House of Commons standards committee published a highly critical report on the conduct of the Conservative MP Owen Paterson. It found Paterson had committed an “egregious” breach of the parliamentary rules against paid advocacy.

The report recommended that Paterson, a former cabinet minister under David Cameron, be suspended from the House of Commons for 30 sitting days. This recommendation was severe enough to trigger a recall petition in his constituency under the Recall of MPs Act 2015.

The saga that followed, dubbed ‘Patersongate’, played a significant role in weakening Boris Johnson’s premiership.

The report, following a two-year investigation, found that Paterson used his position to benefit two companies for whom he was a paid consultant: Randox, a Northern Ireland healthcare diagnostics firm, and Lynn’s Country Foods, a Northern Ireland-based processor and distributor of sausages.

The parliamentary commissioner found that Paterson made three approaches to the Food Standards Agency and four to the Department for International Development on behalf of Randox, and a further seven approaches to the FSA regarding Lynn’s Country Foods. The report stated that “no previous case of paid advocacy has seen so many breaches or such a clear pattern of behaviour in failing to separate private and public interests.”

It added: “Mr Paterson’s remuneration from Randox and Lynn’s amounted to nearly three times his annual parliamentary salary.”

Paterson rejected the findings, claiming that the disciplinary process did not comply with “natural justice” and that he was innocent. He insisted that a “fair process would exonerate me”.

According to parliament’s standards procedure, MPs considered the report in a commons debate held on 3 November. A vote in favour of the report would have seen Paterson suspended from the commons for 30 days and a recall petition triggered in his North Shropshire constituency. This would likely have resulted in Paterson’s ‘recall’ and a by-election.

But the government, led by Boris Johnson, intervened. A three-line whip was imposed instructing Conservative MPs to support an amendment, tabled by Andrea Leadsom.

The amendment noted “concerns expressed about potential defects in the standards system” and provided for a delay to Paterson’s suspension. It called for a new committee to review the entire standards system, including the potential for MPs to have a right of appeal.

Leadsom’s amendment passed by 250 votes to 232. The main motion, as amended, was passed by 248 votes to 221. In total, 13 Conservative MPs defied their party whip to vote against the amendment.

This sparked an immediate and furious backlash from opposition MPs. The government was accused of using its majority to undermine parliamentary oversight and override the findings of a standards investigation.

The government was ultimately forced into a damaging U-turn just the following day, on 4 November. Plans for a new committee were abandoned. Announcing the climbdown, Rees-Mogg acknowledged the vote had “created a certain amount of controversy”. He said that a link “needs to be broken” between Paterson’s case and a wider overhaul of parliament’s disciplinary processes.

On 5 November, Paterson announced his resignation as an MP.

Lobbying scandals: the Ecclestone affair

It has been suggested that those who donate to political parties are likely to be able to gain more privileged access to decision-making.

The so-called ‘Ecclestone affair’, which erupted just six months after Labour’s landslide victory at the 1997 general election, marked New Labour’s first major test – especially of its integrity and commitment to clean up politics. It centred on a £1 million donation made by Formula One (F1) boss Bernie Ecclestone to the Labour Party, and the government’s subsequent decision to propose an exemption for F1 from a planned European Union-wide ban on tobacco advertising.

Ecclestone, who had been a longstanding supporter of the Conservative Party, made his donation in January 1997. This was not made public at the time.

Labour vowed in its 1997 election manifesto to “clean up politics” and reform “party funding to end sleaze”. This rhetoric sought to capitalise on the series of sleaze scandals that plagued John Major’s premiership from 1992 to 1997.

The manifesto also stated: “Smoking is the greatest single cause of preventable illness and premature death in the UK. We will therefore ban tobacco advertising.”

Blair’s party, restyled as New Labour, won 418 seats at the 1997 general election and a commons majority of 179 seats. The landslide represented a swing of 10.3 points from the Conservative to Labour.

Following the election, health secretary Frank Dobson reiterated that the new government would support the EU directive on tobacco advertising.

On 15 May, Dobson told MPs that the ban would “cover all forms of tobacco advertising including sponsorship”.

Blair met with Ecclestone and the head of F1’s governing body, Max Mosley, at 10 Downing Street on 16 October 1997. They threatened that the sport would leave Britain and Europe if the ban was imposed, arguing that as many as 200,000 jobs could be lost.

On 5 November, the government announced proposals to exempt the sport from the ban.

On 10 November, the chancellor, Gordon Brown, told the BBC Radio 4’s Today programme that he did not know whether Ecclestone had contributed to the party.

Later that day, Ecclestone said in a statement: “I met Mr Blair in July 1996 and was very impressed with him and his plans for our country. In January 1997, I was asked by a colleague to make a contribution to New Labour, which I did. I have never sought any favour from New Labour or any member of the government, nor has any been given.”

Labour subsequently admitted that the F1 boss had donated £1 million in January – but promised to return the money. This came on the advice of Sir Patrick Neill, chair of the committee on standards in public life.

This revelation sparked an immediate political firestorm.

On 13 November, Labour admitted that Ecclestone had approached the party with a view to making a further donation after the general election.

In October 1998, Neill’s committee on standards in public life published a report into political party funding. It found that the belief “that elections can only be won by the expenditure (mainly on advertising) of vast sums of money has given rise to something of an arms race.”

The committee recommended the “full public disclosure of donations” of £5,000 or more nationally to political parties, and a ban on anonymous donations to political parties in excess of £50.

The proposals received cross-party support.

Jack Straw, the home secretary, responded that “public confidence in the political system demands that it is open, honest and transparent”.

The Political Parties, Elections and Referendums Act 2000, passed by the Blair government, mandated political parties to report central donations of over £7,500 to the Electoral Commission on a quarterly basis.

In 2008, a year after Blair left office, internal Downing Street briefing notes obtained under the Freedom of Information Act suggested that the decision to pursue the F1 exemption had, in fact, been made on 16 October – immediately following the meeting with Ecclestone.

It was found that on 17 October, Downing Street wrote to Tessa Jowell, the public health minister, stating: “The prime minister would like your ministers to look for ways of finding a permanent derogation for sport, in particular F1.”

A report by the House of Commons public administration select committee into the practice of lobbying, published December 2009, found that there is “at least the perception of a problem, and the concern is one that extends beyond the media.”

It added: “The most prominent recent case of concern was the exemption for Formula One from the ban on tobacco advertising. Bernie Ecclestone, the head of Formula One, donated £1 million to the Labour Party before the general election in May 1997.

“Almost immediately after a meeting in October 1997 between Tony Blair, the then Labour prime minister, and Mr Ecclestone, instructions were issued to the Department of Health to seek an exemption for Formula One from the EU’s proposed ban on tobacco advertising.”

The EU’s tobacco ban was ultimately declared unlawful by the European Court of Justice (ECJ) on 5 October 2000, following appeals from the tobacco industry. The government subsequently sought to fulfil its manifesto commitment with the Tobacco Advertising and Promotion Act, which received royal assent on 7 November 2002. The act contained an exemption for Formula One and other “global sporting events”, which were allowed to continue tobacco sponsorship until 2006.

Lobbying scandals: Neil Hamilton and the ‘cash-for-questions’ affair

The so-called “cash-for-questions” scandal was seen as a defining instance of 1990s political “sleaze”, which contributed significantly to the decline of the Conservative government led by John Major.

On 20 October 1994, the Guardian published a story alleging that Conservative MPs Neil Hamilton and Tim Smith had accepted bribes from Al Fayed. Lobbyist Ian Greer was said to be the middleman in the transactions. Smith was said to have received cash payments of between £18,000 and £25,000; he immediately resigned as a junior Northern Ireland minister.

Hamilton staunchly denied the Guardian’s claims. He joked during a photo opportunity at a school that he needed to declare a biscuit he was eating. Despite his denials, however, Hamilton was forced to resign as minister for corporate affairs on 25 October 1994.

In response to the scandal, Major established the committee on standards in public life (the Nolan committee). The committee’s original terms of reference were to “examine current concerns about standards of conduct of all holders of public office, including arrangements relating to financial and commercial activities, and make recommendations as to any changes in present arrangements which might be required to ensure the highest standards of propriety in public life.”

Hamilton and Greer launched a libel action against the Guardian. However, the case collapsed on 30 September 1996, shortly before the trial was due to begin. The following day, the Guardian ran the famous front-page headline: “A liar and a cheat.”

Hamilton, unlike Smith, refused to stand down from parliament at the 1997 general election. He was ultimately re-selected by his local association in Tatton by 182 votes to 35.

The BBC war correspondent, Martin Bell, stood against Hamilton as an independent “anti-sleaze” candidate. The Labour and Liberal Democrat parties withdrew their candidates to give Bell a clear run.

On 1 May 1997, Bell defeated Hamilton by a majority of 11,077 votes, overturning a notional Conservative majority of over 22,000. Tatton was previously considered the fourth safest Conservative seat in the UK.

Bell was the first successful independent parliamentary candidate elected from outside the party system since 1951.

An official parliamentary inquiry, which began its work prior to the election, concluded in July 1997. The inquiry, led by Sir Gordon Downey, ruled that the evidence “points compellingly to the conclusion that Mr Hamilton accepted cash payments from Mr Al Fayed in return for lobbying services”.

A subsequent report by the House of Commons standards and privileges committee found that Hamilton’s conduct had fallen “seriously and persistently” below the standards expected of MPs.

The report accused Hamilton of a “casualness bordering on indifference or contempt towards the rules of the House on disclosure of interests.”

It added: “Had Mr Hamilton still been a member we would have recommended a substantial period of suspension from the service of the House.”
