The three leaders will convene for separate bilateral meetings and a joint trilateral meeting. There will also be a joint press conference at the Downing Street briefing room.

It comes as the UK allocates an additional $100m directly to the Ukrainian government budget to mitigate financial pressures created by Russia’s unprovoked and illegal invasion.

This grant could be used to support public sector salaries, allowing critical state functions to keep operating, as well as to support social safety nets and pensions for the Ukrainian people. The grant will be provided through the World Bank.

Boris Johnson said: “In the time since Russia’s illegal and brutal assault we have seen the world stand up tall in solidarity with the indomitable people of Ukraine.

“UK aid is already reaching those who need it most, delivering essential supplies and medical support.

“While only Putin can fully end the suffering in Ukraine, today’s new funding will continue to help those facing the deteriorating humanitarian situation.”

The new UK $100m funding announced today comes on top of the UK training 22,000 soldiers, supplying 2,000 anti-tank missiles, providing £100 million for economic reform and energy independence, and providing £120 million of humanitarian aid including £25 million of match funding to the Disasters Emergency Committee (DEC) appeal.

The UK has also guaranteed up to $500 million of Multilateral Development Bank financing. This will unlock further funding in support of the Ukrainian economy.

The UK is proving this support through a World Bank Multi-Donor Trust Fund established this week to support the Ukrainian government.

The government urges other donors to pool their resources in this Trust Fund to ensure efficient and rapid support to the government and people of Ukraine.
