Question to the Ministry of Defence:

To ask the Secretary of State for Defence, how many reservists are currently able to be deployed should the reserve be mobilised.

The requested information cannot be provided without incurring disproportionate cost.

Any reservist, be they a volunteer or an ex-Regular who is liable to be recalled for permanent service, must respond to a call-out notice. As of 1 January 2022, there were 31,920 trained volunteer reservists and 35,188 ex-Regular reservists with a recall liability. In addition, there were also 2,033 sponsored reserves.
