CMS U.K.'s managing partner is making a sideways move into the executive partner position, as the incumbent steps down from the role after a decade. Duncan Weston has spent nearly 10 years as the firm’s first executive partner and oversaw CMS Cameron McKenna's three-way merger with Nabarro and Olswang in 2016. Stephen Millar has been managing partner of CMS U.K. for 10 years and will step into the executive partner role on April 1. He has been at the firm for over 30 years according to his LinkedIn profile. Adrian Bell has already been announced as his replacement. Before his appointment as managing partner, Millar was manager of the energy, projects and construction team. Bell is following the same path having been co-head of the same practice group ahead of his appointment. A firm spokesperson said in a statement that the role will be effective from April 1, 2026. They added that Millar will join the CMS executive team—the team that leads the CMS organisation—alongside Chairman Pierre-Sébastien Thill, Vice Chairman Hubertus Kolster and executive director Isabel Scholes. It is the first change in these roles since CMS U.K. merged with Nabarro and Olswang in 2016. The firm reported revenue of $2.2 billion last year. Since the merger, the firm has nearly doubled revenue and headcount with 77 offices worldwide. Other firms to change their management personnel in recent months include Mishcon De Reya, which named Daniel Naftalin as managing partner in January, and Clifford Chance re-elected its global managing partner Charles Adams for another four years in December.
