NATO Secretary General calls for “quantum leap” in collective defence on visit to the United Kingdom
On Monday 9 June [2025], NATO Secretary General Mark Rutte travelled to the United Kingdom for a bilateral meeting with the British Prime Minister, Keir Starmer, ahead of the NATO Summit in The Hague later this month. During his trip, Mr Rutte also joined British Minister of Defence, John Healey, on a tour of the historic steel production site at Sheffield Forgemasters and delivered a keynote speech at Chatham House.
The Secretary General’s visit came one week after the unveiling of the United Kingdom’s Strategic Defence Review, marking a shift toward warfighting readiness and a ‘NATO first’ defence policy spurred by innovation.
The factory in Sheffield is a key catalyst for British plans to make their defence industry a driver for growth. There, the Secretary General met members of staff, including apprentices, whose specialist skills are contributing to the manufacture of nuclear-grade steel components for Royal Navy submarines.
Later, in London, Mr Rutte met Prime Minister Keir Starmer at 10 Downing Street to discuss increasing defence investment and production as well as continued support for Ukraine. Speaking at Chatham House shortly afterwards, Mr Rutte thanked the UK for “more than seven decades of continuous commitment to NATO” and outlined his priorities for the upcoming NATO Summit.
“This Summit will transform our Alliance,” Mr Rutte stated. “We will build a better NATO, one that is stronger, fairer and more lethal. So that we can continue to keep our people safe and our adversaries at bay.”
He continued with a call to action. “The fact is, we need a quantum leap in our collective defence. The fact is, we must have more forces and capabilities to implement our defence plans in full. The fact is, danger will not disappear even when the war in Ukraine ends.”
The Secretary General stressed that major new investment was needed Alliance-wide and urged a 400% increase in air and missile defence alongside the doubling of NATO’s enabling capabilities including logistics, supply, transportation, and medical support. “We all benefit from the protection our transatlantic Alliance provides and it is vital that every member of NATO pulls their weight” he added.
