Numerous all-party groups (APGs) are set up in Parliament, each having its own terms of reference.
All Party Groups provide an opportunity for parliamentarians to engage with individuals and organisations outside Parliament who share an interest in the subject matter of their Group.
They are not however official parliamentary bodies, and unlike Select Committees, such groups have to avoid preventing themselves as such.
In January 2021, there were All Party Groups dedicated to 130 different countries and territories across the world, ranging from Norfolk Island to Nepal.
In January 2021, there were a further 566 All Party Groups dedicated to different subject areas, ranging from cycling to zoos.
All Party Groups are registered and regulated by House of Commons Authorities.
There is a formal Register of All Party Groups available on the House of Commons website. It lists the officers and Members of every group.
