Question to the HM Treasury:

To ask the Chancellor of the Exchequer, how many staff in his Department have been involved with costing the policies of HM Opposition.

The Treasury does not routinely record information relating to the allocation of individual members of staff to specific tasks such as opposition costings. However, all work undertaken by HM Treasury officials (or officials from other departments) on opposition costings was completed in line with the guidance on ‘Costing the policies of Opposition parties’ set out in the Directory of Civil Service Guidance. Final versions of the costing documents produced by Civil Servants have been published online at https://www.gov.uk/government/publications/opposition-policy-costings-2024.
