The local businessman has been at the helm for the last 16 years, after buying the club from Dave Whelan at the end of 2007.
He will officially resign on November 30, with Mike Danson taking over as the Warriors’ new 100 percent owner, after being involved as a shareholder since the summer of 2020.
Meanwhile, Professor Chris Brookes will become the new Wigan chairman, having recently been appointed as vice, following on from a 40-year career in the NHS.
