UK Needs 10 Years to Rebuild Defence, Former Chief Warns

Former Defence Chief Delivers Dire Warning on UK Military Readiness

Lord Jock Stirrup, the former chief of defence staff who served under prime ministers Tony Blair and Gordon Brown, has issued a stark warning to Prime Minister Keir Starmer, declaring that the United Kingdom requires a full decade to rebuild its defence capabilities even with immediate leadership and investment.

'Badly Exposed' Nation Requires Complete Mental Shift

In an exclusive interview with The Independent, Lord Stirrup stated that Britain finds itself "badly exposed as a country" and needs "a complete change of mentality" to adopt a proper war footing. The former air marshal emphasised that he fully agrees with the damning assessment made by Labour peer Lord Robertson regarding the current state of UK defences and the government's failure to adequately address the crisis.

Lord Stirrup, who worked closely with Lord Robertson during the latter's tenure as defence secretary and NATO general secretary, warned that the situation has deteriorated to such an extent that the UK must undertake a "graduated" increase in defence spending to rebuild its defence production capacity, otherwise risking significant inflation within the sector.

Ten-Year Timeline for Recovery

The former military leader was unequivocal about the timeline required for recovery, stating: "We require 10 years of sustained investment in defence to restore our position." He cautioned that this decade-long process does not mean the government can postpone critical decisions until the final years, as he believes the current administration seems to think.

Lord Stirrup outlined two primary requirements for rebuilding UK defences: replenishing stores, munitions, and other consumables of war that have been depleted, particularly due to supplies sent to Ukraine; and developing "an agile, innovative and rapidly scalable defence base" throughout Western Europe, extending beyond traditional defence companies.

Leadership Crisis and Tough Decisions

The man who oversaw UK military operations in Afghanistan and Iraq expressed frustration with what he perceives as a lack of leadership from Sir Keir's government. "I see no signs at the moment of the required determination and leadership in the government that's required to do this because, of course, it requires extremely difficult choices," Lord Stirrup stated.

Reflecting on Lord Robertson's warning that welfare spending needs to be redirected toward defence, he added: "We all understand the pressures on finances. We all understand the pressures on the economy, not least from the rapidly expanding benefits bill, which is a whole different subject by itself. But we expect our leaders to lead and that means when times are tough, making the tough decisions. We didn't force these people to run the country. They wanted to do it."

Government Response and Ongoing Delays

The intervention follows a hard-hitting report from the former senior military commander written for Policy Exchange, in which he warned that the UK can no longer rely solely on its nuclear deterrent for defence without supporting it with other military hardware.

Prime Minister Starmer has defended his government's record, insisting during Prime Minister's Questions that he is making record investments in UK defence. However, Lord Stirrup countered this claim by noting: "It is easier to make record increases when defence spending was at a record low."

The crisis unfolds as the prime minister faces growing criticism over delays to crucial defence decisions. The long-awaited Defence Investment Plan remains on his desk while the Treasury and Ministry of Defence continue to clash over priorities. During parliamentary exchanges, opposition figures pressed Sir Keir on when the Defence Investment Plan would be published, calling for its release before the end of the parliamentary session.

Sir Keir responded by reaffirming his government's commitments, stating: "Last February, that was seven months after taking office, I took the decision to increase defence spending from 2.3 per cent to 2.6 per cent, paid for by my difficult decision on overseas aid. Last June, at the NATO summit, I committed to raising core defence spending to 3.5%. Last November, the budget committed record funding to defence. I reaffirm those commitments now."

The prime minister added that the strategic defence review represents a 10-year blueprint for national security and that the Defence Investment Plan would implement this blueprint, promising its publication "as soon as possible."
