Starmer must take baton from Macron in effort to sway Trump on Ukraine

UK and France need to convince US to align with them over Ukraine, while at the UN Trump openly sides with Russia

Keir Starmer, when he visits the White House on Thursday, will have to pick up the many loose threads left by another chaotic day of diplomacy in the US in which America voted with Russia at the UN to protect Vladimir Putin from criticism over the invasion of Ukraine, and then saw Trump make assurances that Putin was happy for European forces to enter Ukraine - only to be contradicted by Moscow hours later.

Emmanuel Macron, the French president, has been working in lockstep with the UK in a way the two countries have failed to since Brexit, and the aim was for the two leaders of Europe's major military powers to use their visits this week to operate as a pincer movement pressing Trump to question Putin's trustworthiness and more broadly to accept that America's future still lay as a partner with Europe.
