Healey's resignation, announced on Thursday, represents a significant setback for Prime Minister Starmer, who is already facing mounting political pressure and calls from some members of the ruling Labour Party to step down.

The United Kingdom's Defence Secretary, John Healey, has resigned from Prime Minister Keir Starmer's government, accusing the administration and the Treasury of failing to commit sufficient resources to the country's military at a time of growing global security threats.

Healey's resignation, announced on Thursday, represents a significant setback for Prime Minister Starmer, who is already facing mounting political pressure and calls from some members of the ruling Labour Party to step down.

In a resignation letter addressed to Starmer, Healey said the government's proposed Defence Investment Plan falls far short of what Britain requires to address escalating international security challenges.

According to Healey, repeated efforts to secure greater defence funding were unsuccessful because the Treasury was unwilling to allocate the level of resources demanded by the country's armed forces.
