UK backs outgoing Dutch PM Rutte to become next NATO chief

His term was extended in July last year for a fourth time as the alliance opted to stick with an experienced leader rather than try to agree on a successor with Russia's war in Ukraine raging on NATO's doorstep. Diplomats say Rutte is currently the only official candidate for the post.

Britain is backing outgoing Dutch Prime Minister Mark Rutte to succeed Jens Stoltenberg as the next secretary general of the NATO alliance, the Foreign Office said on Thursday. Stoltenberg's successor when he steps down in October will take office at a crucial time, tasked with sustaining NATO members' support for Ukraine's costly defence against the Russian invasion while guarding against any escalation that would draw the alliance directly into a war with Russia.

Depending on the outcome of November's U.S. presidential election, the next NATO boss may also have to deal with a second term for Donald Trump, who recently once again called into question his commitment to defending NATO allies. Rutte, who is considered the favourite to fill the role, signalled his interest in the job last year.

The Foreign Office said Rutte was a well-respected figure across NATO with serious defence and security credentials, and someone who would ensure it remained strong and prepared for any need to defend itself. NATO leaders are appointed by consensus requiring the support - or at the least no opposition - from all its 31 members. Sweden is currently poised to become the alliance's 32nd member.

Rutte, the Netherlands' longest-serving leader, unexpectedly announced his departure from Dutch politics in July, but remains in post as a caretaker leader while coalition negotiations continue following a Nov. 22 election. Stoltenberg, a former Norwegian prime minister, has served as NATO chief since 2014. His term was extended in July last year for a fourth time as the alliance opted to stick with an experienced leader rather than try to agree on a successor with Russia's war in Ukraine raging on NATO's doorstep.

Diplomats say Rutte is currently the only official candidate for the post. Estonian Prime Minister Kaja Kallas and Latvian Foreign Minister Krisjanis Karins have also signaled interest but have not been presented formally as candidates, according to diplomats.
