The United Kingdom is preparing to commit significant resources to a proposed post-ceasefire stabilisation force in Ukraine, with Defence Secretary John Healey estimating the cost at “well over £100 million.”
In remarks delivered at the Mansion House in London, Healey revealed that the UK has already accelerated millions of pounds in preparatory funding to ready its armed forces for rapid deployment once a ceasefire materialises. The envisioned mission — part of a “coalition of the willing” led by the UK and France, encompassing around 30 nations — would focus on securing Ukraine’s airspace and maritime zones, training Ukrainian troops and supporting mine-clearing operations in the Black Sea.
Healey stressed that this potential deployment is distinct from the UK’s current military aid package for Ukraine, pointing out that the new cost estimate covers the initial entry package — troops, aircraft and logistics — and does not yet include the full lifecycle of the operation.
The statement comes amid heightened discussion of a possible diplomatic summit between U.S. President Donald Trump and Russian President Vladimir Putin, which could pave the way for a ceasefire in the nearly three-year war. The UK’s readiness to deploy reflects a strategic choice to support Ukraine not just through arms delivery but by being involved in long-term peace enforcement.
However, the plan still faces considerable uncertainty: the timing and shape of any ceasefire remain unclear, and the exact scope, duration and cost of the stabilisation force may evolve significantly. Critics also warn that £100 million is a modest figure compared to the scale of the conflict and eventual peacekeeping effort that may be required.
