LONDON (AP) — U.K. Defense Secretary John Healey unexpectedly resigned on Thursday, saying the government isn’t willing to spend enough on the military at a time of “rising threats.”

The resignation is another blow to embattled Prime Minister Keir Starmer, who is already facing demands from Labour colleagues to step down.

Healey told Starmer in a letter that the government’s Defense Investment Plan falls “well short of what is required at this dangerous time.”

Publication of the plan has been delayed amid reports of disagreement between the defense ministry and the Treasury.

Starmer has pledged to boost U.K. defense spending to 2.5% of gross domestic product by 2027 and 3% by 2034. But many in the military say that isn’t fast enough.

“You have been unable, and the Treasury has been unwilling, to commit the resources that the nation needs to defend the country at this time of rising threats,” Healey wrote in his resignation letter.

He said that the spending plan put forward by the Treasury would see defense spending rise to just 2.68% in 2030 after hitting 2.6% next year.

Healey said that isn’t enough with growing demands on defense and British military commitments, citing the Iran war, Russia’s all-out invasion of Ukraine and threats from Moscow.

“I am now left with no other option than to submit my resignation,” he said.

Healey has been U.K. defense secretary since the Labour Party government was elected in July 2024, and he’s regarded as a capable and serious minister.

He has played a key role in bolstering international support for Ukraine and assembling a multinational coalition to help guarantee security if a ceasefire is reached. Healey also has helped spearhead a maritime security force that would help keep the Strait of Hormuz open to shipping if the Iran war ends.

The United Kingdom and other NATO member nations have faced pressure from U.S. President Donald Trump to increase military spending. Trump has long questioned the value of the military alliance and complained that the United States provides security to European countries that don’t pull their weight.

The U.K. military is also seeking to reverse years of decline in the face of an increasingly assertive Russia, which fully invaded its neighbor Ukraine on Feb. 24, 2022, and increasingly tests the defenses of European nations with overt and covert activity.

NATO Secretary-General Mark Rutte, informed of Healey’s resignation by The Associated Press during a news conference in Brussels, said that Healey is someone “I respect very much.”

“What we are seeing all over the alliance is countries increasing their defense investments, and of course it is not easy, because in the end there is always a trade-off with other expenses, which are also important,” Rutte said.

Healey’s resignation is likely to further stoke talk that Starmer’s days as prime minister are numbered. Already bruised by a series of missteps since Labour returned to power less than two years ago, Starmer has faced calls within his party’s ranks to stand down.

He appears to have been unable to bridge the gap between Healey’s department and Treasury chief Rachel Reeves over defense spending.

Greater Manchester Mayor Andy Burnham is widely expected to challenge Starmer for the leadership, if he returns to Parliament in a June 18 special election.
