Yorkshire chairman Steve Denison has resigned from his position with the club with immediate effect.
Denison was the club's chairman for the three years and said in a statement he was resigning with "deep regret".
"To say I'm heartbroken is a massive understatement at what has already been an incredibly difficult time for me and my family," the statement continued.
Chief executive Mark Arthur added: "It is a really sad day, not only for Yorkshire but for the game as a whole.
"Steve has achieved so much, both as a director and chairman over the last six years. We will greatly miss his input and contribution."
