The Victorians called Britain and Germany “awkward cousins.” These days, Keir Starmer is trying to revive that Anglo-German amity as part of a broader reset with the European Union. The prime minister has wooed Chancellor Friedrich Merz since the Christian Democrat leader took power in Berlin last year, leading to the signing of the Kensington Treaty nine months ago.

The treaty was designed to fill the gap in bilateral relations after Brexit and give the Anglo-German relationship more power with an increasingly bellicose Russia. But how much influence do Starmer and Merz have over an erratic American President Donald Trump — and can the E3 (the U.K., Germany and France) really influence Trump’s war with Iran?

Host Anne McElvoy talks to Susanne Baumann, Germany’s ambassador to London, in her first interview since she was appointed last September.
