At Lancaster House, a 19th century mansion adjacent to Buckingham Palace, it felt like a moment of truth for Europe, as the continent’s biggest powers gathered to try to rescue something from a crumbling postwar order.
Sir Keir Starmer and French President Emmanuel Macron, working in tandem, had a clear message in London: Europe has to prove to Donald Trump that it is part of the solution to the crisis on its own continent, not part of the problem.
As one of the UK prime minister’s allies put it before the meeting, there was no alternative to patching things up with the White House: “The PM will bring people together and politely make sure they realise that there is only one negotiation in town — and that’s President Trump’s.”
