The Competition and Markets Authority (CMA) is a UK government agency responsible for promoting competition and preventing anti-competitive practices in markets. It ensures that businesses operate fairly, benefiting consumers and the economy. The CMA investigates mergers, enforces consumer protection laws, and addresses issues like monopolies and cartels. The CMA also conducts market studies to identify areas where competition may be lacking. By doing so, it aims to improve market conditions and enhance consumer choice. The agency works closely with other organizations, such as the Office of Fair Trading and the European Commission, to maintain fair competition standards.
