The Office of Fair Trading (OFT) and the Competition Commission (CC) have agreed a Memorandum of Understanding (MoU) on co-operation over the review of undertakings and commitments imposed on the parties to a merger, a monopolist or markets. The OFT is under a statutory duty to keep these undertakings and orders under review and to advise on whether they require variation or revocation. The MoU is intended to clarify the review and decision making process and develop clear lines of communication between the OFT and the CC.
