It’s the most important international relationship the UK has, and for decades has been referred to as “special”. Since the second world war, the UK and the US have considered themselves the closest allies, working together for shared values, with any resentments, differences of opinion or cross words kept to private channels.

But now Donald Trump is back and he seems keen to throw the usual world order of alliances and enmities into chaos. Keir Starmer’s first meeting with the US president comes at a crucial juncture for Europe, with the future of Ukraine in the balance. “The stakes at the moment could not be higher,” says the Guardian’s diplomatic editor, Patrick Wintour.

He tells Michael Safi what advice Starmer should be receiving from his advisers, including to keep things simple and not to be boring. And what Starmer will be trying to achieve, especially in terms of clarifying Trump’s recent outpourings around Ukraine. “I think the key thing to find out is where does this man lie ideologically,” Patrick says. But if Trump has no allies, only transactional relationships, how much can Starmer hope to achieve during this meeting?
