Castleford Tigers chief executive Steve Ferres has resigned with immediate effect from the Super League club.

Ferres, the first chief executive of York City Knights whom he helped to re-establish as a club after the collapse of the Wasps, was appointed in the position last July and was a lifelong supporter of the Tigers.

However, Ferres, who also played for York RFLC, stepped down, citing differences with the club’s board over changes that he believes need to be made.

He said in a statement: “As CEO I believe I have a moral obligation to everyone associated with the Tigers from its staff to the players and right through to its loyal fans.

“Since the board is not in a position to support the multitude of changes that I believe must take place now in order for Castleford to continue to compete at Super League level, I feel I have no option other than to offer my resignation.

“I am an extremely proud man and a proud Castleford man so rest assured that this decision was not made lightly.”

• Steve McCormack has quit as Swinton coach to spend more time with his family.

McCormack led the Lions to the Championship One title in 2011. They have lost all three matches so far this season, including at York ten days ago.
