United Kingdom: Merger Control

This article examines the significant institutional, procedural and enforcement changes to UK merger control that occurred on 1 April 2014, when the Enterprise and Regulatory Reform Act 2013 (ERRA 2013) entered into force. On that date, the Competition and Markets Authority (CMA) assumed the functions of the Competition Commission (CC) and the competition and some consumer protection functions of the Office of Fair Trading (OFT),1 including merger control under the Enterprise Act 2002 (EA 2002). It also reviews the principal OFT, CC and CMA decisions, and Competition Appeal Tribunal (CAT) and the Court of Appeal judgments, in merger cases between June 2013 and May 2014.
