  Mark Friend

Partner

London

Mark is head of the London Antitrust group. He has some 30 years’ 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, economic regulation and antitrust litigation and he has particular expertise in advising on regulatory and competition issues in regulated sectors including energy, water, air traffic control, postal services and rail.

He has acted on several of the ground-breaking and notably complex cases in the 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 (and the subsequent appeal before the European Court).

Market investigation work includes acting for one of the Big Six energy firms in the CMA Energy market investigation, and acting for a leading insurer in the CMA investigation into Private Motor Insurance.
