Boris Johnson has issued stern criticism of Donald Trump’s Ukraine peace proposals in one of his first apparent censures of the US president, saying under his terms the Ukrainians would “get nothing”.

The former British prime minister, a strong supporter of Ukraine who remains close to Ukraine’s president, Volodomyr Zelenskyy, has previously said there is “method in the madness” of Trump’s approach and that he believed the US president could bring peace.

But in a post on X, Johnson criticised the apparent terms of a deal that Trump is pushing Kyiv to accept.

Overnight, Trump accused Zelenskyy of jeopardising what he claimed was an imminent peace deal to end the war in Ukraine as he gave the clearest hint yet that the US would be willing to formally recognise Russia’s seizure of Crimea as part of any agreement.
