Dan Jarvis has been appointed the new Defence Secretary, replacing John Healey who resigned in protest over the Defence Investment Plan's funding levels. Jarvis, a former Parachute Regiment officer, previously served as Security Minister.

The resignation of the Defence Secretary and a junior minister over funding levels highlights significant internal divisions regarding national security investment, potentially impacting military readiness and strategic planning.
Dan Jarvis has been appointed the new Defence Secretary, following the resignation of John Healey. Healey dramatically quit his post on Thursday morning, citing insufficient funding within the Defence Investment Plan (DIP) as the reason for his departure. In his resignation letter, Healey stated that the allocated funds, projected to increase defence spending from 2.6% to 2.68% of GDP by 2030, amounted to less than half of what army chiefs deemed necessary and would compromise national security.
Jarvis, a former officer in the Parachute Regiment with service in Kosovo, Northern Ireland, Iraq, and Afghanistan, was previously the Security Minister. His appointment came shortly after junior defence minister Al Carns also resigned, stating he could not defend an "inadequate" investment level. Labour MP Pamela Nash also resigned, expressing concerns about trust and the government's ability to be bold on critical issues.
Prime Minister Keir Starmer defended the DIP, asserting it would provide the necessary resources for the military, clarity for the defence industry, and strategic investments for the long term. He stated the plan would enable the armed forces to modernize and be equipped with the tools needed to deter enemies.
