Weil Gotshal & Manges' London-based private equity partner Will Rosen is set to leave the firm, having handed in his notice today (3 July).
Rosen, who has been with the firm since its London launch in 1996, is one of Weil's most prominent private equity partners, along with office managing partner Mike Francies, former Travers Smith partner Mark Soundy and partner Marco Compagnoni, who joined from Lovells in February 2006.
Rosen is said to be re-evaluating his career options over the summer.
He has been right-hand man to Francies and worked on several Lion Capital deals, including the house's £1.27bn purchase of Cadbury Schweppes' European drinks business with the Blackstone Group in 2005.
Weil will have five private equity partners in London after Rosen's departure: along with Francies, Soundy and Compagnoni, there are partners Jonathan Wood and Ken Schiff.
Compagnoni told The Lawyer: "He's a great friend and it's sad. He's also a great practitioner, so in that sense there is sadness, but in terms of our capability we’re still strong."
