Donald Trump has spent the week turning the world upside down again – launching a trade war with China and claiming America will take over the Gaza Strip – and Prime Minister Sir Keir Starmer is scrambling to work out how best to respond to the American president.

Relations between presidents and prime ministers aren’t always easy, even without Elon Musk weighing in with his views.

Keir Starmer is heading to Brussels, becoming the first British prime minster to attend a European Union leaders’ meeting since the U.K. left the bloc five years ago.

Sir Keir Starmer and Donald Trump agreed to meet “soon” in their first phone call since the US president ’s inauguration. In the 45-minute call, Sir Keir praised the US president for his “role in securing the landmark ceasefire and hostages deal in Gaza”, Downing Street said.
