(Reuters) - Sports betting and gaming group Entain ( GMVHF ) said on Thursday Chair Barry Gibson would step down by September-end after more than four years in the role, although could potentially leave earlier if a CEO gets appointed for the group.

Entain ( GMVHF ), the owner of Ladbrokes and Coral betting shops, said interim CEO Stella David will replace Gibson on his retirement.

Last December, Entain ( GMVHF ) CEO Jette Nygaard-Andersen stepped down following reports that some shareholders were unhappy with her leadership.

Gibson,72, became chair in February 2020 and has played an integral role in the group's transformation from GVC Holdings, and also in the resolution of the HM Revenue & Customs probe into its legacy Turkish unit.

His departure comes at a time when the gambling firm has reportedly hired advisers to oversee the possible sale of its overseas brands, including Netherlands-based BetCity, which was acquired by Entain ( GMVHF ) last year.
