James Elston has resigned as chief operating officer of Wakefield Wildcats.
Mr Elston had been involved with the club for more than 12 years, and had held the role of chief executive from 2010 until this summer.
During that time he brought former chairman Andrew Glover to the club, who helped to rescue the club from liquidation and successfully apply for a Super League licence in 2011.
Mr Glover was replaced by new chairman Michael Carter last month.
In a statement on the Wildcats’ website, Mr Elston said: “Having spent nearly 12 years at the club I have made the difficult decision to resign.
“Having originally been tasked with the job of finding new investment to save the club from liquidation in 2010, we defied all odds to stay in Super League. I have some great memories and thank all the staff and fans for their support over the years.
“Whilst I will be moving on I will always have the club at heart and will continue in my role as Trustee of the Wakefield Community Trust. I wish Michael Carter and everyone associated with the club all the very best for the future.”
Mr Carter said: “I would like to personally thank James for all his considerable efforts, especially over the last three years.
“His enthusiasm, knowledge and manner, especially on match days, will be sorely missed. Everyone at the club wishes James well in all his future endeavours.”
