Jones Day's London managing partner Russell Carmedy and European head of private equity Michael Nouril have left the firm to join Proskauer Rose, after the pair handed in their notice last week (1 April).

Corporate partner Carmedy has led Jones Day's UK practice since the firm merged with Gouldens in 2003, when Carmedy was co-managing partner of the UK firm. A highly-regarded corporate lawyer, his practice focuses on cross-border M&A and leveraged private equity and he has advised on deals in sectors including natural resources, healthcare and technology.

Nouril, who has also been at Jones Day since the 2003 merger, advises private equity and hedge funds, entrepreneurs and family offices.

Both will now join US firm Proskauer Rose, which recently held aborted merger talks with SJ Berwin.

One ex-Jones Day partner commented: "Proskauer wants to merge with a UK firm and has brought in Carmedy with a remit to make it happen."

John Phillips, formerly Jones Day's UK head of corporate, is taking over as the partner in charge of the London office. London capital markets partner Giles Elliott will take over the UK corporate chief role.

Jones Day and Proskauer declined to comment.
