Former security minister Tom Tugendhat has warned that the United Kingdom is increasingly vulnerable to hostile threats due to a significant decline in its military capabilities. Speaking ahead of the summer parliamentary session, Tugendhat emphasized the need for stronger national defences to deter adversaries and prevent conflict. Drawing on his experience as a military officer in Afghanistan’s Helmand province, he described the current state of the British armed forces as inadequate to meet modern security challenges.

Tugendhat highlighted concerns over the reduction in the size and readiness of the British Army, noting that the true “deployable force” may now number only a few thousand troops. He also expressed alarm at the shrinking Royal Navy, warning that Britain lacks sufficient maritime capacity to defend its shores effectively. The former Conservative leadership contender pointed to the erosion of “credible artillery” as symptomatic of a broader weakening of defence capabilities.

His concerns extend to Russia’s ongoing use of covert and violent tactics on UK soil, including alleged assassinations and efforts to sow division within British society. Tugendhat suggested the UK is already engaged in a form of conflict with Moscow, which he described as using “incredibly violent means” against the country. He further warned of the risk that Russia could target critical undersea communications and energy infrastructure, causing both economic disruption and potential financial market panic due to the UK’s perceived inability to defend these assets.

Tugendhat invoked the example of the Falklands War during the Thatcher era as a successful demonstration of Britain’s power projection and deterrence capabilities. He argued that maintaining a credible military presence not only protects the nation’s interests but also signals strength to potential adversaries. However, he acknowledged that successive governments, including his own Conservative Party, bear responsibility for decades of defence cuts. He called for urgent political will to reverse this trend.

Political instability, particularly within the opposition Labour Party, was identified by Tugendhat as a further impediment to addressing national security challenges. The uncertainty surrounding key leadership and ministerial roles, including the Defence Secretary and Chancellor, complicates long-term planning at a time when decisive action is needed. He expressed concern that this internal turmoil creates gaps in policymaking that could be exploited by hostile actors.

Separately, commentary from political figures has underscored the urgency of rebuilding the British military amid global instability, including conflict in Ukraine and uncertainty over the United States’ commitment to NATO. Critics argue that the current Labour government has been slow to prioritize defence spending, raising fears that Britain’s weakened forces could embolden adversaries and undermine national security. Calls have been made for full funding of the Ministry of Defence’s requests to restore key capabilities and maintain the country’s deterrent posture.

Both Tugendhat and other commentators stress that safeguarding Britain’s future depends on restoring strength to its armed forces and maintaining national unity. Tugendhat warned that internal divisions, such as movements pushing for Scottish independence—which could jeopardize the country’s nuclear deterrent—represent a fundamental security threat. The broader consensus points to the need for comprehensive, well-resourced defence strategies supported by stable political leadership.
