Welcome to the latest edition of our newsletter which explores recent competition law developments across the UK and EU.

In this edition, we examine recent decisions from the Competition Appeal Tribunal, namely its judgment in the first trial under the UK’s collective actions regime, and its approval of further settlements of collective actions. We also take a look at the UK’s concurrency regime for competition law enforcement and consider whether it remains fit for purpose.

On the mergers side, we review the recent decision in Vodafone/Three – in which the CMA, unusually, accepted behavioural remedies – and consider whether, at a time when the CMA is being pushed by the Government to support its growth agenda, this signifies a broader shift in the CMA’s approach. And with the UK’s new digital markets competition regime having entered into force (and the first two sets of investigations already having been announced), we examine the CMA’s likely approach to deploying its new powers.

Finally, for those who may have missed last month’s circular, we include our roundup of the competition law developments to look out for in 2025, in both the EU and UK.

Towards the end of 2024, the Tribunal approved further collective settlements in the “roll-on, roll-off” car shipping collective action brought by Mark McLaren. This allowed two further defendant groups to avoid participating in the trial of these proceedings, which commenced on 13 January 2025.

Three is the magic number: CMA approves Vodafone/Three merger

Following a Phase 2 review, the CMA accepted behavioural remedies to clear this telecoms merger. Despite having taken a different approach in previous cases in this sector, the CMA ultimately determined that the package offered by the parties was sufficient to address the substantial lessening of competition that it found would result from the merger.
