Andrew Francis takes over from Vince Flower, who has retired after more than 35 years with the group, formerly known as Shearings.
Francis has previously held operational and senior sales roles at Marriott International.
Richard Calvert, SLG chief executive, hailed Francis’s ability and track record, adding: “I’m sure with his wide range of hotel sector experience he will bring some new ideas to the hotel division, as well as continuing the great job Vince Flower did over the years for the group.”
