International arbitration heads at Freshfields Bruckhaus Deringer, Herbert Smith Freehills and Berwin Leighton Paisner are among five solicitor advocates to be appointed Queen’s Counsel (QC).

Included in the group is Constantine Partasides, Freshfields’ head of international arbitration in London, who is leaving the magic circle firm to set up an arbitration boutique with Paris-based disputes partner Georgios Petrochilos and former Freshfields arbitration head Jan Paulsson.
