Volodymyr Zelenskyy is heading to Downing Street once again, but Prime Minister Sir Keir Starmer will be keen to make this meeting more than just a photo op.
On Monday the prime minister will welcome not only the Ukrainian president, but also E3 allies France and Germany to discuss the state of the war in Ukraine.
French President Emmanuel Macron and German Chancellor Friedrich Merz will join Sir Keir in showing solidarity and support for Ukraine and its leader, but it's the update on the peace negotiations that will be the main focus of the meet up.
The four leaders are said to be set to not only discuss those talks between Ukraine, the US and Russia, but also to talk about next steps if a deal were to be reached and what that might look like.
Ahead of the discussions, Sir Keir spoke with the Dutch leader Dick Schoof where both leaders agreed Ukraine's defence still needs international support, and that Ukraine's security is vital to European security.
But while Russia's war machine shows no signs of abating, a warm welcome and kind words won't be enough to satisfy the embattled Ukrainian president at a time when Russian drone and missile attacks continue to bombard Kyiv.
What is the latest in negotiations?
Over the weekend, Mr Zelenskyy said he had discussed "next steps" with US President Donald Trump's advisers and was "determined to keep working in good faith".
"The American representatives know the basic Ukrainian positions," Mr Zelenskyy said in his nightly video address. "The conversation was constructive, although not easy."
But on Sunday evening, ahead of an event at the Kennedy Center, President Trump said he was "disappointed" with Mr Zelenskyy, as was asked about the next steps in Russia-Ukraine talks following negotiations.
He said: "We've been speaking to President Putin and we've been speaking to Ukrainian leaders, including Zelenskyy, President Zelenskyy.
"And I have to say that I'm a little bit disappointed that President Zelenskyy hasn't yet read the proposal. That was as of a few hours ago.
"His people love it. But he hasn't - Russia's fine with it. Russia's you know, Russia, I guess, would rather have the whole country when you think of it. But Russia is, I believe, fine with it, but I'm not sure that Zelenskyy's fine with it. His people love it but he hasn't read it."

On Saturday, Keith Kellogg, Trump's outgoing Ukraine envoy, had told the Reagan National Defence Forum that efforts to resolve the conflict were in "the last 10 metres".
Kremlin spokesman Dmitry Peskov praised new US security strategy over the weekend, adding that Russia hopes this would lead to "further constructive cooperation with Washington on the Ukrainian settlement".
