‘A leading competition law set with superior skills through all levels of seniority’, Monckton Chambers operates at the forefront of high profile competition cases, including antitrust, class actions and public undertakings.

George Peretz KC successfully acted on behalf of the Civil Aviation Authority concerning appeals regarding Heathrow Airport’s charges to airlines, while Josh Holmes KC defends Google in a £7bn collective action alleging anti-competitive practices in relation to mobile searches. In January 2024, Daniel Beard KC led Daisy Mackersie before the CAT in Le Patourel v BT, the first opt-out class action to reach trial and having potentially significant implications for the UK collective proceedings regime. Ronit Kreisberger KC acts for the claimant in Cabo v MGA, a complex abuse of dominance and collusion claim which raises difficult questions at the intersection of competition and IP law.
