Freshfields Bruckhaus Deringer has appointed Simon Marchant (pictured) as its new London head of corporate while Simon Priddis has been chosen to lead the City antitrust, competition and trade (ACT) practice.

Marchant succeeds Julian Long who was recently appointed London managing partner after his predecessor Mark Rawlinson stepped down from the role in December. Marchant previously co-headed Freshfields' London M&A business. He previously led the firm's Asia business.

Priddis succeeds Rod Carlton who has served two terms and will return to full time fee-earning. Priddis has particular expertise in the financial services and healthcare fields, and was former co-head of the firm's global healthcare group. Prior to joining Freshfieldshe was a senior official at the UK competition regulator. Both Marchant and Priddis will serve three-year terms which take effect from today (1 May).

Freshfields managing partner David Aitman said: "These appointments see the leadership of our London corporate and competition practices handed over, to two massively skilled and very well regarded partners. Freshfields' corporate and ACT practices are globally recognised as market leaders – I have no doubt that we will see these positions consolidated under Simon and Simon's guidance of the London teams.

"I would also like to extend my thanks on behalf of the firm to Julian and Rod for their thoughtful, dedicated and determined management of both London practices over the past three years, during which time they demonstrated first-class leadership and expertise in helping maintain the excellent market standing we enjoy today."
