According to press reports, Dave Rowntree of Blur filed the UK equivalent of a class action lawsuit against PRS (the UK version of ASCAP and BMI). The claim is a “collective proceeding” filed with the UK’s antitrust tribunal. The class action established a website to communicate about the claim with interested parties. The website says:

Collective Proceedings Against PRS for Music

If You Were a Writer Member of the Performing Right Society at Any Time Since 9 March 2017,
a Proposed Legal Claim Could Affect Your Rights

On 27 February 2024, the claim was brought against PRS that asks the Competition Appeal Tribunal for permission to go forward as an “opt-out collective action.”  The claim concerns the way in which PRS distributes, or permits to be distributed, certain royalty sums that are called in the PRS Rules and Regulations (“PRS Rules and Regulations”) and the PRS Distribution Policy Guide terms such as  “unmatchable” (including “copyright control”), “non-distributable”, and “unclaimed” and colloquially referred to within the music industry as “Black Box” royalties. The majority of Black Box royalties are royalties belonging to PRS writer members but when the Black Box royalties are distributed, the distribution is heavily skewed in favour of publishers who receive a large portion of the writer share. In other words, Black Box royalties are transferred from PRS writer members and given to PRS publisher members who have no right to those royalties.

David Rowntree seeks to represent the class of PRS writer members who have lost money arising from the proposed claim.

Of course, the Mechanical Licensing Collective is sitting on hundreds of millions of black box money for the US as well, and may end up being the defendant in a separate class action at some point in the future.
