The Competition and Markets Authority (CMA) is the competition regulator in 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.
