Al Carns, the UK Armed Forces Minister, resigned from Prime Minister Sir Keir Starmer's government on 12 June, citing what he described as a fundamental failure to adequately fund and equip Britain's military. The departure deepens a visible rift within the administration over national security spending and defence preparedness.

The Resignation and What Triggered It

Carns announced his exit in a post on X, stating that Number 10 had repeatedly refused to heed his warnings about military underfunding. 'We owe those who serve the UK the kit to do the job and the loyalty to stand by them when it's done. We are failing on both,' he wrote. In a formal resignation letter to the Prime Minister, he added: 'It has become clear to me that the change I had pushed for is not going to come.'

His resignation follows that of former Defence Secretary John Healey, who similarly clashed with Starmer over the defence budget, arguing the proposed spending levels 'fall well short' of what is required to protect the country. Two high-profile defence departures in close succession signal a pattern of internal dissent that the government can no longer easily contain.

Carns' Core Criticisms

A former Royal Marine, Carns drew on his military background to argue that Britain's procurement policies are dangerously out of step with modern warfare. Citing the conflict in Ukraine as a reference point, he warned: 'The character of conflict is changing faster than our procurement can keep up with. We are still purchasing capability suitable for the last war while our adversaries arm for the next one.'

He was particularly pointed in his assessment of the government's Defence Investment Plan (DIP), from which he distanced himself: 'While I had no hand in the Defence Investment Plan, that distance does allow me to say plainly that it is not built for the threat we face. It is neither transformative enough nor sufficiently funded.' He added that Britain was 'asking our Armed Forces to operate in a more dangerous world on a budget written for a calmer one.'

On Veterans and the Northern Ireland Legacy Bill

Carns also used his resignation letter to criticise the Northern Ireland Legacy Bill, calling it 'unfit for purpose' and warning that it risks failing the very veterans it was designed to protect. The criticism adds another dimension to his departure, framing it not merely as a budget dispute but as a broader concern about the government's treatment of serving and former military personnel.

'I cannot in good conscience stand at the dispatch box and defend a level of investment I know to be inadequate to the task,' he stated. 'A serious country funds its defence to meet the threat it actually faces, not the threat it wishes it faced.'

Political Fallout and What Comes Next

The back-to-back resignations of Healey and Carns are expected to intensify parliamentary and public pressure on the Starmer government over its defence posture, particularly as NATO allies push member states toward higher military spending and security concerns across Europe continue to mount. The government has not yet named a replacement for Carns, and the Ministry of Defence faces a period of uncertainty at a moment of heightened global tensions.
