Question to the Cabinet Office:

To ask His Majesty's Government whether any written undertakings regarding immunity from disciplinary action have been issued to Crown servants giving evidence to inquiries since 2005; and if so, how many, broken down by department and public body.

The Cabinet Office does not hold this data. It is not Civil Service practice to provide immunity from disciplinary action in such circumstances. The Cabinet Secretary or departmental Permanent Secretaries may, where appropriate, provide letters of assurance to those giving evidence to inquiries to encourage them to provide open and honest answers to questions posed.
