The Competition and Markets Authority (CMA) works 'to promote competition for the benefit of consumers, both within and outside the UK. Our aim is to make markets work well for consumers, businesses and the economy.' (Quotation taken from the CMA website).
The CMA acquired its powers on 1 April 2014 when it took over many of the functions of the Competition Commission (CC) and the Office of Fair Trading (OFT).
The UK Competition Appeal Tribunal (CAT) "is a specialist judicial body with cross-disciplinary expertise in law, economics, business and accountancy whose function is to hear and decide cases involving competition or economic regulatory issues." (Description from CAT's homepage.)
