Ukrainian President Volodymyr Zelensky has urged Donald Trump and Sir Keir Starmer to meet and find common ground, after the US president's repeated criticism of the UK prime minister.

In an exclusive interview with the BBC after talks with Sir Keir, the Ukrainian president said that while he would not tell Trump what to do, the pair should meet to "re-load the relationship".

A war ignited by US and Israeli strikes on Iran has spilled into a diplomatic row after Trump's reprimanding of the Nato allies and Starmer's supposed lack of military action.

Zelensky warned against division among Western leaders and said he had a "very bad feeling" about the impact of the war in Iran on Ukraine.

"I would really like President Trump to meet with Starmer... so that they have a common position," he said.

In his latest attack on Tuesday, Trump branded Starmer "no Winston Churchill" and said that while he thinks the UK prime minister is a "nice man" he is "disappointed".

Sir Keir's response held firm, insisting the UK will not be drawn into a wider war, with Downing Street reiterating an "enduring" US-UK relationship.

Zelensky also said he had a "very bad feeling" about the impact of the Middle East conflict on the war in Ukraine, saying negotiations towards peace are being "constantly postponed. There is one reason - war in Iran".

Sir Keir welcomed Zelensky to Downing Street on Tuesday - the latest stop on the Ukrainian leader's tour of European capital cities.

Zelensky visited Paris last week and travels to Madrid on Wednesday. The visits come as the Middle East conflict overshadows Ukraine's four-year fight against Russia's full-scale invasion.

"I think it's really important that we are clear that the focus must remain on Ukraine," said Sir Keir.

As part of Zelensky's visit to London, the Ukrainian leader addressed MPs in Parliament.

"The regimes in Russia and Iran are brothers in hatred, and that is why they are brothers in weapons," Zelensky said. "And we want regimes built on hatred to never, never win in anything. And we want no such regime to threaten Europe or our partners."

Among those in the audience in a packed Westminster committee room were Sir Keir, Nato Secretary-General Mark Rutte, Defence Secretary John Healey and leaders of opposition parties.
