Volodymyr Zelensky has been to Buckinghamshire to meet with Rishi Sunak at Chequers.
The Ukrainian president and the prime minister were seen strolling together after exiting a Chinook chopper.
The president’s most recent stop on his European tour is Britain, following a journey to Paris for a meeting with his French counterpart, Emmanuel Macron.
He will “meet my friend Rishi” for “substantive negotiations face-to-face and in delegations,” according to the leader of Ukraine.

A statement on Twitter this morning read: ‘Today – London. The UK is a leader when it comes to expanding our capabilities on the ground and in the air.
‘This cooperation will continue today. I will meet my friend Rishi. We will conduct substantive negotiations face-to-face and in delegations.’

It also follows meetings in Berlin and Rome, and comes three months after his first trip to London since the start of the war.
At the time, he attended an audience with King Charles and address Parliament in February.
It is yet unclear what the two leaders will discuss, but Mr Sunak has pledged the UK’s ‘sustained support’ for Ukraine.
The PM said: ‘This is a crucial moment in Ukraine’s resistance to a terrible war of aggression they did not choose or provoke.
‘They need the sustained support of the international community to defend against the barrage of unrelenting and indiscriminate attacks that have been their daily reality for over a year. We must not let them down.
‘The frontlines of Putin’s war of aggression may be in Ukraine but the fault lines stretch all over the world. It is in all our interest to ensure Ukraine succeeds and (Vladimir) Putin’s barbarism is not rewarded.
‘That is why the UK is sustaining our support to Ukraine – from tanks to training, ammunition to armoured vehicles.
‘And this message of solidarity will ring loud in all my meetings with fellow world leaders in the days ahead.’
This comes after Mr Sunak and defence secretary Ben Wallace announced that the government had agreed to authorise the supply of long-range cruise missiles.
That decision was welcomed by Mr Zelensky as a ‘significant enhancement’ of the efforts in the war.
The visit by Mr Zelensky comes ahead of a G7 gathering in Hiroshima, Japan later this week, which will be attended by Mr Sunak.
