Jay Willey today officially ended her association with the Bulls after citing “irrevocable differences” between her and the club’s board of directors.

The Telegraph & Argus revealed in March how the Bradford businesswoman was poised to pump a “six-figure” fee into the club in return for a significant shareholding.

The 41-year-old from Holme Wood, who owns the European arm of cosmetics firm Kroma, which is currently embroiled in a high-profile legal battle with the Kardashian family, vowed to bring a touch of “glitz and glamour” to the Bulls.

Despite playing a prominent hands-on role at the club in recent weeks, the investment did not materialise following what is believed to be a breakdown in relations with the Bulls’ management team.

Willey said in a statement: “I am sad to be announcing my official withdrawal of all involvement with the Bradford Bulls.

“My reasons for this are a number of irrevocable differences between the board and I which has left me with no other course of action.

“I want to take this opportunity to wish Franny and the players all the best for the remaining season.”

The Bulls are in action tonight as they head to London Broncos in the Tetley’s Challenge Cup fifth round.
