The UK's Digital Markets, Competition and Consumers (DMCC)
Act 2024 establishes a new regulatory framework aimed at promoting
competition and innovation in digital markets, while safeguarding
consumers and businesses from unfair practices by dominant
technology firms. This regime is overseen by the Competition and
Markets Authority (CMA) and came into effect in January
2025.
On 14 January 2025, the CMA launched the first
investigation under the regime, focused on Google's
activities in search and search advertising.
On 22 January 2024, the CMA announced that it would
also investigate Apple and Google's position regarding their
‘mobile ecosystems', which includes operating systems,
app stores and browsers that operate on mobile devices.
