LONDON — Keir Starmer has confirmed the U.K. will hit NATO’s target of spending 5 percent of GDP on defense by 2035 as he prepares to meet other western leaders in The Hague.

The British prime minister hailed the move as “an opportunity to deepen our commitment to NATO and drive greater investment in the nation’s wider security.”

Making the pledge alongside the publication of a new national security strategy, Starmer specified the U.K. was on course to reach 4.1 percent of GDP on defense by 2027.

He previously vowed to spend 2.6 percent of the country’s economic output on defense by 2027-2028 by slashing the U.K.’s overseas aid budget and including intelligence spending in the sums for the first time.

Until now, the U.K. government has only spoken of an “ambition” to spend 3 percent on defense at some point during the next parliament.

The higher figure of 5 percent will consist of a 3.5 percent boost for core defense costs while an additional 1.5 percent will be spent on resilience and security, according to government officials.

‘National interest’

The national security strategy brings together several strands of work commissioned by Starmer on entering government, including the Strategic Defense Review and the China audit.

It is expected to say that attaining energy security and tackling smuggling gangs are key to national security, while prioritizing the threat from “gray zone” attacks on cyber networks and critical infrastructure.

“We must navigate this era of radical uncertainty with agility, speed and a clear-eyed sense of the national interest to deliver security for working people and keep them safe,” Starmer said. 

The U.K. prime minister will join allies for the NATO summit in the Netherlands on Tuesday as European leaders urge the U.S. and Iran to de-escalate and renew diplomatic efforts.
