Competition and Markets Authority (CMA)
The UK competition and consumer protection authority.
Overview
The CMA enforces competition law, reviews mergers, runs market studies, and has direct consumer law enforcement powers and a digital markets regime for firms with strategic market status.
Its powers include supervising and examining the organisations it oversees, investigating and imposing penalties and bringing or referring criminal cases.
In the United Kingdom it works at national level, alongside Ofcom.
