Britain’s political strains burst into the open when Defence Secretary John Healey resigned after a fierce row over military funding, charging that Prime Minister Keir Starmer had failed to back the country’s security needs at a moment of growing danger.

The surprise departure, delivered alongside a sharply critical public letter, adds to the pressure bearing down on Mr Starmer as he confronts the prospect of a leadership challenge. It also lays bare the government’s central dilemma: how to increase defence spending when the public finances are already under severe strain.

For months, Britain’s defence and finance ministries have been in protracted negotiations over how to answer mounting calls for higher military spending. The impasse has pushed back Britain’s ‌Defence Investment Plan, which had been expected to ⁠be published last year.

Senior military figures have argued the blueprint is urgently needed as the threat picture worsens, with Russian activity in British waters becoming a regular concern. Yet the government is also trying to bring down debt while coping with an overall tax burden that is at its highest level in decades.

“You have been unable, and the Treasury has been unwilling, to commit ⁠the resources that the nation needs to defend the country at this time of rising threats,” Mr Healey said ‌in his letter to Mr Starmer.

The delay has also angered Britain’s defence industry, which says the absence of a clear plan leaves companies unable to make ‌long-term investment decisions.

The UK is contending with the US pivoting away from protecting Europe while at the same time the US-Israeli war with Iran exposed Britain’s lack of military readiness, with its navy unable to immediately deploy an advanced warship to the region.

The defence plan is ⁠designed to set out funding for military equipment and services so the armed forces can move towards a state of “warfighting ⁠readiness”, and Mr Starmer said yesterday it would be published before a NATO summit beginning on 7 July.

“Your DIP financial settlement – which I was first given in full on Monday afternoon this week – falls well short of what is required for defence and the country at this dangerous time,” Mr Healey said.

“I am being forced to make decisions that would reduce the readiness of our forces and increase the risk to personnel on operations, and could make the country ‌less safe.”
