Remit and powers of select committees

Select committees are cross-party groups of MPs or Lords established by either House for the duration of a Parliament. The work of the Commons committees is governed by Standing Orders (SOs) of the House of Commons; these rules set out their membership, remit and powers and any changes to the rules must be approved by the House.

Committees decide upon their own subjects for inquiry within the broad scope of their remit. They seek evidence from people and organisations with an interest in their inquiries and anyone can submit evidence to the inquiry. The Commons Library briefing, Select Committees: evidence and witnesses, reviews the power of select committees “to send for persons, papers and records”.

Departmental select committees

In the House of Commons there are 20 departmental select committees that shadow the work of the Government departments. Their remit is set SO No.152:

Select committees shall be appointed to examine the expenditure, administration and policy of the principal government departments as set out in paragraph (2) of this order and associated public bodies. Other Commons select committees cover aspects of public policy such as public spending, and the internal administration of the House.

Membership of committees and election of chairs

Membership of select committees reflects party membership of the House as a whole. Since June 2010, chairs of departmental select committees have been elected by secret ballot of the House. Also elected by secret ballot are the chairs of the following select committees [SO No.122B]:

  • Environmental Audit
  • Petitions
  • Public Administration and Constitutional Affairs
  • Public Accounts
  • Procedure
  • Standards

In addition, the Chair of the Backbench Business Committee is elected at the start of each Session in accordance with SO No.122D.

The number of MPs on the committee is determined by Standing Orders and is noted in the table below along with the party affiliation of the chair and a link to each committee’s website which gives the full membership of the committee and the role of the committee.

The full report lists chairs of select committees in the current Parliament. The spreadsheet  provides information on chairs since 2010.

The practical arrangements for the election of committee chairs by secret ballot are set out in, Select committees: election of chairs and members.
