We've taken a closer look at the current distribution of the UK's top lawyers, which markets have been growing the fastest, and how large a presence US firms now have in the UK. Using publicly-available data tracked by Pirical Legal Professionals (PLP) , here's a snapshot of the UK legal market in 2025.

Yesterday, McDermott Will & Emery and Schulte Roth & Zabel announced their plans to merge. The combination would create a law firm of around 1,600 attorneys and $2.8 billion of revenue.

If approved, the merger would unite McDermott's broad expertise in healthcare, dispute resolution, and corporate law with Schulte's deep focus on hedge funds, private capital, and financial regulation.
