William Hill chief executive James Henderson is stepping down, the bookmaker has announced.
The company’s chief financial officer, Philip Bowock, will step up to replace him on an interim basis.
Henderson has worked for William Hill over 30 years, covering the retail, online and international businesses.
William Hill said the search for a replacement has been instigated.
Chairman Gareth Davis said: “We would like to thank him for his significant contribution and we wish him all the best for the future.
“Philip has a clear set of priorities as Interim CEO, principally the continued turnaround of the Online business. We will confirm a successor in the coming months.”
It has been a tough couple of months for William Hill.
Its share price closed yesterday on 275p, down from more than 400p in March, when it warned of a £25m fall in online profits in 2016.
