Question to the Ministry of Defence:

To ask the Secretary of State for Defence, how many military posts allocated for British Armed Forces personnel within NATO remain unfilled as of 1 April 2025.

The UK is one of the largest contributors of personnel to NATO, underlining our commitment to deterrence and defence of the Euro-Atlantic Area, with personnel deployed in over twenty-one countries.

The UK consistently has one of the highest post fill rates in NATO. As of 1 April 2025, the UK’s post allocation was 1,053, of which 8% were unfilled. This is due to new long-lead posts recently being included in data, as well as normal churn.
