Weil Gotshal & Manges’ City office has bagged a first-time instruction for Japanese camera and medical devices company Olympus, advising opposite magic circle giant Allen & Overy (A&O) on the camera-maker’s £1.03bn bid for Gyrus Group.

The referral came from the US law firm’s New York office, where Olympus has been a client for several years, with the London arm winning the role following a presentation to the company.
