Competition and Markets Authority

The Competition and Markets Authority (CMA) is the principal competition regulator in the United Kingdom. It is a non-ministerial government department in the United Kingdom, responsible for strengthening business competition and preventing and reducing anti-competitive activities. The CMA launched in shadow form on 1 October 2013 and began operating fully on 1 April 2014, when it assumed many of the functions of the previously existing Competition Commission and Office of Fair Trading, which were abolished. The CMA also has consumer protection and digital markets regulation responsibilities.
