Starmers domestic troubles deepened after a over the Iran conflict earlier this year. The British prime minister initially resisted U.S. requests to use British bases during military operations against Iran, prompting Trump to criticize him publicly, saying: “This is not Winston Churchill that were dealing with,” on March 3.

John Healey defended Starmer publicly before the resignation announcement, saying, “More instability is not in Britains interest. Our full focus must be on security.”
The political crisis also intensified scrutiny over Starmers broader leadership and decision-making.
His government faced criticism over Britains handling of the ongoing U.S.-Iran crisis, with opponents accusing him of appearing indecisive after reports that the U.K. initially resisted some American military requests before partially backtracking.
