Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what proportion of planned defence expenditure between 2026 and 2035 will be allocated to the Defence Nuclear Enterprise.

The Defence Investment Plan sets out £63.6 billion of planned investment in the Defence Nuclear Enterprise between financial years 2026-27 and 2029-30, excluding workforce costs.

The proportion of the Ministry of Defence's budget spent on the Defence Nuclear Enterprise will increase over the next four years to between around 20% and 25%.

The Defence Investment Plan sets out the Government's current priorities and strategic intent for investment in Defence over the coming decade, underpinned by detailed spending plans from 2026-27 to 2029-30. Spending plans beyond that will be subject to future Spending Reviews.
