After the UK leaves the EU it will no longer be part of the EU competition system.
The European Commission will no longer begin investigations into the UK elements of mergers or cases involving anti-competitive conduct in the UK.
Instead, the Competition and Markets Authority (CMA) will be responsible for investigating mergers and cases of anti-competitive conduct which affect the UK market.
The CMA will also take jurisdiction of the UK aspects of live EU antitrust and merger cases that the European Commission was investigating before Brexit, but which have not yet been decided. Businesses should be aware that it is possible that there will be no agreement on jurisdiction over these cases.
Businesses operating in the UK must continue to comply with UK competition law as they do now and those operating in the EU must comply with EU competition law.
