Introducing Big CAT Watch: our UK competition collective proceedings tracker

We are delighted to announce that we have launched Big CAT Watch: our UK competition collective proceedings tracker.

Big CAT Watch is our new platform providing insight and expertise on UK collective proceedings. If you are interested in collective proceedings or puns about lions, our new tracker will be catnip for you.

It shows collective proceedings order (CPO) applications in the UK Competition Appeal Tribunal (CAT) visualised using several different metrics. It also contains our analysis and comment on the trends that can be seen in the data.

Big CAT Watch has been inspired by our colleagues’ Platypus platform containing UK merger control analysis.  

The information on Big CAT Watch is up-to-date as of 1 September 2025 and we will be releasing regular updates.
