Friday, February 5, 2021 UK merger control – a new dawn? The start of 2021 coincides with the end of the transition period following the UK’s withdrawal from the EU. In turn, this brings about the most significant change to UK merger control since the introduction of the current UK regime by the Enterprise Act 2002. This is because, as reported in previous editions of Competition Currents, one of the key consequences of the end of the transition period is that the EU’s “one-stop shop” merger control regime no longer covers the UK: new M&A transactions are now potentially subject to parallel investigations in Brussels and London.
