“Britain backs war on Iran” is the headline in the Daily Telegraph, which leads with the decision to allow the US to use UK military bases to attack Tehran’s missile sites. The paper says Sir Keir Starmer’s previous refusal to grant such permission caused him to face pressure from some within his own party, and put him at odds with other world leaders. It adds that the initial denial led to President Trump withdrawing his support for the deal to hand the Chagos Islands to Mauritius. Similarly, the Times highlights claims the move “angered” Trump. It characterises Sir Keir’s latest decision as a U-turn.
