Question to the Cabinet Office:

To ask His Majesty's Government how many statutory and non-statutory inquiries they have undertaken since 2005, and what were their (1) length, (2) cost, (3) sponsoring department, and (4) subject matter.

Since 2005, our records show that His Majesty’s Government has established 19 non statutory inquiries and 23 statutory inquiries under the Inquiries Act 2005 on a broad range of subject matters. 28 of the total 42 inquiries have been completed. Several of these statutory inquiries had previously been established as non statutory inquiries or inquests. The length of completed inquiries in this period ranges from 7 to 99 months and published costs vary significantly from between £0.2m and £194m. Most Whitehall departments have sponsored public inquiries. Further information can be found on inquiry and departmental websites and in the National Archives.
