John Healey has stepped down as defence secretary in a dramatic protest against the government’s military spending plans, delivering a blistering personal attack on Prime Minister Keir Starmer. His resignation marks another significant blow to Starmer’s leadership.
Scathing Resignation Letter
In a strongly worded letter to the prime minister, Healey declared that the long-awaited defence investment plan “falls well short of what is required for defence.” He warned that the decisions he would have been forced to take “could make Britain less safe.”
The former defence secretary did not hold back in his criticism, accusing Starmer of failing to prioritise national security. The letter has sent shockwaves through the Labour Party and Westminster.
Background to the Row
The dispute centres on the government’s military spending commitments, which Healey argued were inadequate given current global threats. Sources suggest Healey had been pressing for a more ambitious funding package for months.
Nosheen Iqbal discussed the fallout with the Guardian’s policy editor, Kiran Stacey, who noted that the resignation could trigger further unrest among Labour MPs over defence policy.
Reactions and Implications
Political analysts say the resignation is a serious challenge to Starmer’s authority, especially on matters of national security. The prime minister’s office has yet to issue a detailed response, but allies insist the government remains committed to a robust defence posture.
The resignation also raises questions about the future direction of Labour’s defence policy and whether Starmer can hold his party together ahead of the next election.
