  Mark Friend



Mark is head of the London Antitrust group. He has extensive experience of counselling and representing clients on complex mergers and strategic alliances, cartel, dominance and market investigations, both at EU and national level. His practice also encompasses state aid, antitrust litigation and economic regulation.

He has extensive experience of acting for clients in highly sensitive and complex areas and has particular expertise in advising on regulatory and competition issues in regulated sectors including the air traffic control, water, energy, postal services and rail sectors.

Mark has acted on several of the groundbreaking and notably complex cases in the new UK merger regime, including the landmark Lloyds/HBOS, Co-op/Somerfield and Boots/Alliance UniChem cases. He also has high profile experience in European merger control advising Sun Microsystems on its merger with Oracle, and Thomson on its acquisition of Reuters (now the subject of an appeal before the European Court).

"Mark Friend has particular expertise within the energy and utility sectors. He has a strong reputation in the market." Chambers UK 2015 (Competition)

"Mark Friend is viewed by peers as a solid option for merger control advice. Clients value his understanding of heavily regulated sectors including the energy and water industries." Chambers UK 2014 (Competition/European Law)

"Friend has ‘a personal authority and credibility which makes people take notice’." Legal 500 2013 (EU and competition)

He was listed as one of only five antitrust lawyers globally who are recognised as ‘client service leaders’ in the 2010 BTI Client Service All-Stars report.
