Al Carns, the Minister for Veterans of the United Kingdom (UK) and a decorated former Royal Marines officer, resigned from his post yesterday, following the earlier departure of Defence Secretary John Healey. Both resignations have highlighted mounting concerns within the Ministry of Defence and among military leadership that the government’s current defence policies and funding priorities may be leaving British armed forces insufficiently prepared for emerging global threats.

In his resignation letter, Carns stated that the government is failing to provide the armed forces with both the equipment necessary to conduct operations safely and the broader support required to maintain readiness under increasingly dangerous conditions. He specifically criticised the long-delayed Defence Investment Plan (DIP), arguing that it is neither adequately funded nor sufficiently structured to meet the pace and scale of modern warfare. He warned that, while military threats are evolving rapidly, the resources and planning available to the UK’s forces remain calibrated for a much calmer security environment.

The urgency of these concerns has been underscored by operational events earlier this year. During escalating tensions in the Persian Gulf involving Iran, the Royal Navy was reportedly unable to deploy any major warship immediately. HMS Dragon, once assigned to the theatre, took more than ten days to reach Cyprus, while other vessels were unavailable due to maintenance or previous commitments, leaving critical shipping routes and regional allies without a British maritime presence. Analysts have described this as a clear demonstration of structural limitations in personnel, logistics, and munitions supply, reflecting broader challenges across all domains of the armed forces.

Recent assessments indicate that the UK’s military, while maintaining high-quality assets, suffers from insufficient numbers and support systems across the army, air force, navy, cyber, and space operations. Cyber and space capabilities, although central to contemporary operations, remain underfunded, and the country’s nuclear deterrent relies heavily on American support for both infrastructure and maintenance. The armed forces are further constrained by personnel shortages, maintenance backlogs, and a procurement system that is slow to adapt to emerging threats, creating a risk that operational ambitions outstrip the practical capabilities available.

Funding constraints are central to these challenges. Current projections show defence spending rising from 2.60% of GDP in 2027 to 2.68% by 2030, which is insufficient to maintain credible operational readiness or the ability to deploy its armed forces across the globe. Without decisive prioritisation of logistics, personnel, and operational sustainment, investment in advanced systems and equipment may fail to address the fundamental readiness gaps.

Carns and Healey were both regarded as highly competent and respected figures within the defence establishment, and their resignations cast doubt on Prime Minister Keir Starmer’s capacity to manage national security effectively.
