- considering the proposals for the annual plan
- the annual performance and concurrency reports
- making rules of procedure for merger reference groups, market reference groups, and special reference groups.
The CMA board’s rules of procedures (https://www.gov.uk/government/publications/cma-board-rules-of-procedure) set out how often the board will meet, quorum, procedure at meetings, and other formal information.

The board has authorised the Chair, CMA staff, and the Panel Chair to carry out specific functions on its behalf. Please see the board authorisation document (https://www.gov.uk/government/publications/cma-board-rules-of-procedure/annex-e-authorisation-of-staff-of-the-cma-and-named-cma-inquiry-chairs) for detail.

The board has agreed a conflicts of interest policy (https://www.gov.uk/government/publications/cma-board-rules-of-procedure/appendix-f-conflicts-of-interest-policy) for the CMA, which applies to board members, panel members, and members of staff. As part of this, a register of interests for board members (https://www.gov.uk/government/publications/cma-register-of-interests) has been developed and published on the CMA website.

CMA panel

Some functions of the CMA must be performed by the CMA panel. Panel members have clearly defined responsibilities and act as fresh decision-makers in phase 2 market investigations, merger inquiries and regulatory references and appeals. Panel members may also be appointed to antitrust (Competition Act 1998) case decision groups.

Members are appointed to the CMA panel by the Department for Business and Trade for up to 8 years. They are appointed through open competition for their experience, ability and diversity of skills in competition economics, law, finance and business.

The panel consists of 27 members and includes a small group of Inquiry Chairs. The CMA Chair, with the consent of the board, appoints a CMA Panel Chair who has overall responsibility for leading the panel, and who allocates Inquiry Chairs and panel members to each case. At least one panel member (usually the Panel Chair and one other Inquiry Chair) is also appointed to the CMA board.

The board’s oversight role does not extend into the substance of decisions by groups on phase 2 work. The groups make their decisions independently of the board. The board is kept informed about resourcing, efficiency, the application of CMA policy and the staff processes that support the work of the panel.
