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.

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 is heading to Brussels to join a gathering of European Union leaders – the first time a British prime minister has done so since Brexit. Starmer is heading over the English Channel for talks focused on defence and security co-operation and will also meet Nato secretary general Mark Rutte.
