What is happening
Defence Secretary John Healey resigned on 11 June in protest over the government's proposed Defence Investment Plan, according to the BBC . In his resignation letter, the BBC reports Healey criticised the plan as insufficient to meet the armed forces' minimum resource requirements . Hours later, Armed Forces Minister Al Carns also stepped down, stating the plan was "not built for the current threat and not sufficiently funded" .
The BBC reports the government is preparing to announce a £13.5bn funding increase for the Ministry of Defence over four years, less than the £28bn requested by the department . According to the BBC, the plan is backloaded, with pressure on operations and readiness in the first two years, and is being funded by cutting capital budgets across government departments by 1% . Sir Keir Starmer defended the plan as delivering "an unprecedented increase in spending in a sustainable and fair way", the BBC reports .
The resignations represent the seventh and eighth ministerial departures in the past month , part of what multiple outlets describe as a broader Labour Party leadership crisis . The BBC reports health secretary Wes Streeting resigned on 14 May , and according to The Guardian, a Labour MP stood down to allow Greater Manchester mayor Andy Burnham to contest a by-election in Makerfield . The BBC reports Burnham confirmed his candidacy on 19 May and has said he would seek to enter any leadership contest . Channel 4 News reports former Welsh first minister Mark Drakeford called for Starmer to step down , whilst the BBC reports Drakeford endorsed Burnham for prime minister .
Why it matters
Healey's resignation is particularly damaging because, as the BBC notes, he was one of Starmer's most loyal cabinet allies . The Guardian describes his departure as occurring "at the worst possible time" for the prime minister , coming amid intense internal party debate over Starmer's leadership. The New York Times characterises the resignation as "a blow to Starmer" , whilst The Telegraph suggests it "torpedoes Starmer" and ends his hopes of remaining Labour leader .
The defence funding dispute has wider European implications. The Guardian reports the UK, France, and Italy are not increasing defence spending due to concerns about undermining lenders' confidence in their national debt . According to The Guardian, the UK has pledged to reach 3% of GDP for defence spending only by 2029, whilst France and Italy are expected to hit 2.5% by the decade's end . The BBC reports the government faces calls to increase defence spending to 3% of GDP by 2030, but is planning 3.5% only by 2035 .
The Guardian reports Russia is conducting a covert war of sabotage, assassinations, cyber-attacks, and drone intrusions against Europe , lending urgency to the funding debate. The publication notes the prime minister warned of the risk of more wars in Europe by 2030 . The Guardian also reports the UK chose to stay out of a planned Defence, Security and Resilience Bank, leaving Canada and Luxembourg to lead .
Who is involved
John Healey served as defence secretary until his resignation on 11 June. The BBC reports Dan Jarvis has been appointed as his replacement . Al Carns was Armed Forces Minister until stepping down the same day . Sir Keir Starmer is the Prime Minister and Labour Party leader facing pressure to resign. According to the BBC, Healey asked other defence ministers to remain in their posts despite his own departure .
Andy Burnham, currently Greater Manchester mayor, is positioning himself as a potential successor. The BBC reports he confirmed he would seek to enter any Labour leadership contest and is now the Labour candidate in Makerfield following the standing-down of the sitting MP . According to The Guardian, Starmer will not attempt to block Burnham from standing .
Wes Streeting, who resigned as health secretary on 14 May according to the BBC , has confirmed he will stand if a leadership race is triggered, The Guardian and The Independent report . However, Labourlist reports polling suggests Streeting would lose a leadership contest against Starmer . Rachel Reeves, as Chancellor, is central to the funding decisions that prompted Healey's criticism, according to The Guardian .
What to watch next
The Defence Investment Plan is yet to be released and was due to be announced before a NATO summit in Turkey, which the BBC reports was set as a public deadline . Whether the new defence secretary, Dan Jarvis, can secure additional funding or whether the government proceeds with the disputed plan will determine if further resignations follow.
The mechanics of a potential leadership challenge remain uncertain. Labourlist is tracking which Labour MPs are calling for Starmer to go and who is still backing him . The Guardian reported on 16 May that the week had left Britain's PM "looking like an interim leader" , suggesting momentum may be building against him. The BBC reports the government is facing calls to resign within its own party following poor election results , though specific electoral performance data appears in analysis by Persuasionuk .
Whether Burnham can successfully pivot from mayor to MP, and whether a sufficient number of MPs and party members would support his or Streeting's leadership bid, will shape the crisis's trajectory. The Economist argued on 14 May that "Sir Keir Starmer has failed abjectly. He should go" , indicating editorial pressure alongside internal party tensions. The Guardian described Westminster on 14 May as waiting "in frenzied limbo" , a characterisation that remains apt as the crisis deepens with each ministerial departure.
