Sir Keir Starmer has secured an invitation to meet with President Trump in Washington, but the growing divergence of UK and US positions on key topics will put their warm personal relationship under pressure. The UK has been doing its best to reinforce its support for Ukraine, with Starmer expressing his backing in a phone call and insisting that there can be no talks about Ukraine without Ukraine. However, the UK's commitment to increasing defense spending and the issue of Ukraine's accession to NATO are points of disagreement with the US. The PM will need to navigate these delicate negotiations while also addressing the threat of trade tariffs that could cost the UK economy £24bn.
