The Week in Defence: 2–8 June 2025

by CMS Team on 09 June, 2025

The past week may go down as one of the busiest weeks in Defence, with not only the publication of the long-awaited Strategic Defence Review (SDR), but also with the news that the UK has agreed to significantly increase its defence spending to 3.5% of GDP, after bowing to pressure from NATO. However, this will apply further pressure on the Government, after questions were raised over how the SDR would be funded, with ministers refusing to outline a timeline to spending 3% of GDP on defence. In other headlines, it was revealed that Air Chief Marshal Sir Richard Knighton will replace Admiral Sir Tony Radakin as the next Chief of the Defence Staff.

Coming Up This Week:

NATO Secretary-General Mark Rutte is at Chatham House in London on Monday, calling for a 400% increase in the bloc’s air and missile defences. Sir Keir Starmer will meet with Rutte to discuss NATO’s prospective new 5% spending target, which is due to be implemented at the NATO summit later in June.

On Wednesday (11th), Chancellor Rachel Reeves will unveil the Spending Review, setting out how much money each government department will receive over the next 3-4 years. Health and defence are expected to be winners. However, it is unlikely that any increase in the defence budget will go far enough to meet the recommendations set out in the SDR.

It’s also a busy week for the House of Commons Defence Committee, who will be hearing from Chief of the Defence Staff, Admiral Sir Tony Radakin, on Tuesday (10th), and the reviewers of the Strategic Defence Review on Wednesday (11th).
