The Digital Markets, Competition and Consumers Act 2024 has finally been enacted. It introduces significant changes to U.K. merger control and antitrust rules, establishes a new consumer protection regime and introduces a groundbreaking new digital markets regime. Businesses with operations in the U.K. ‐ particularly those active in digital and consumer sectors ‐ should begin preparing now to ensure they are in full compliance when the rules start to take effect, for the most part expected in stages from autumn 2024.
