To note: concurrency arrangements were introduced in the UK in their current form by the Enterprise and Regulatory Reform Act 2013 and took effect from 1 April 2014. Under ERRA 2013, these sector regulators have concurrent competition powers to enforce against breaches of the UK on anti-competitive agreements and abuses of a dominant position under Chapter I and Chapter II respectively of the Competition Act 1998, as well as to conduct market studies and make market investigation references under the Enterprise Act 2002.   Mergers do not fall within the scope of concurrency, although the CMA often receives input and assistance from the regulators when investigating a merger in a regulated sector. The Secretaries of State for Business, Energy and Industrial Strategy and Digital, Culture, Media and Sport have relevant functions in relation to public interest cases.
