British defence minister John Healey has quit in a dispute over military spending, accusing Prime Minister Keir Starmer of failing to commit the government resources that are needed to defend the country at a time of heightened threat.
The unexpected resignation on Thursday, accompanied with a scathing public letter, compounds the pressure on Starmer when he is facing a likely leadership challenge and exposes the crisis at the heart of government - how it can ramp up defence spending when there is no money to spare.
Britain's defence and finance ministries have been locked in talks for months over how to meet rising demands to expand military spending, delaying Britain's Defence Investment Plan, which was expected to be published in 2025.
