UK Becomes Fourth Jurisdiction to Introduce Dedicated Digital Platform Regulation, with More Jurisdictions Likely to Follow

On 23 May, the UK Parliament passed the Digital Markets, Competition and Consumers (DMCC) Bill.  The new DMCC Act will bring about some of the most significant reforms to competition and consumer protection law in the UK in decades. Among other major reforms, it introduces a dedicated regime that provides for specific conduct rules for large digital platforms. The UK therefore becomes the fourth jurisdiction—after the EU with its Digital Market Act (DMA), Germany with its s.19A rules, and Japan with its new smartphone bill (also passed on 23 May)—to introduce rules that target a handful of the largest digital firms.[1]

On 21 May 2024, the UK Government published updated guidance on the application of the National Security and Investment Act (NSIA).  This includes:

On 11 April 2024, the CMA published an update paper (the Update Paper) in relation to its initial review of AI Foundation Models (FMs).  An accompanying technical update report (the Technical Update Report) was published on 16 April 2024, providing further detail on market developments and feedback from stakeholder engagement.  These updates follow the CMA’s September 2023 initial report into the same topic (the Initial Report).

The following post was originally included as part of our recently published memorandum “Selected Issues for Boards of Directors in 2024”.

Antitrust in 2023 was marked by a series of policy developments—some still nascent, some ripe for enforcement for the first time.  In the U.S., the FTC and DOJ finalized their drastically transformed merger guidelines.  In the EU, landmark new digital regulations became applicable for the first time.  And the UK government introduced a bill promising major new digital and consumer protection rules. 

On 20 November 2023, the Digital Markets, Competition, and Consumers Bill (DMCC) cleared the report stage and an expedited third reading in the House of Commons, at which a series of significant amendments were passed. 

The Digital Markets Act (DMA) is a landmark piece of legislation granting unprecedented powers to the European Commission to regulate large digital platforms. The DMA targets platforms that operate as gatekeepers between businesses and users, hold an “entrenched and durable position,” and operate one or more core platform services (CPSs).

The explosion in the development of generative AI has been referred to as an “Oppenheimer” moment.  Just last week, a group of more than 350 executives and scientists jointly stated that “[m]itigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war.”  And more than 1,000 tech leaders have called for a moratorium on AI development until regulations governing its safe use are devised.
