West Ham United's Joint-Chair David Sullivan has quit his position with immediate effect amid serious historic allegations. The 77-year-old's decision comes after more than 16 years on the club's board and follows fan protests directed at him. Sullivan has also resigned as a director of both WH Holding Limited and West Ham United Football Club. He denies any illegal conduct and has taken the decision to step down to avoid disruption to the club while he addresses the matter privately. Interim Chief Executive Officer Karim Virani will continue to lead the club's day-to-day operations. Sullivan plans to take legal action against the BBC over reports he claims are false. He believes the entire process has been fundamentally unfair and completely lacking in any due impartiality. Sullivan's departure is a significant blow to the club, but he hopes West Ham United can move forward in the right direction. He thanks everyone connected with the club for their loyalty and friendship. West Ham United will always remain close to his heart, and he has total confidence that the Board of Directors and Virani will do everything they can to take the club forward. The club will provide an update on the future structure of the Board of Directors in due course. Sullivan's statement denied any wrongdoing and expressed his intention to sue the BBC for libel. He claims the allegations levelled against him have been sensationalised by the media. Sullivan is a private man, and those who personally and professionally know him understand who he is and what he stands for. He is not the person the media has decided to paint him as. The false allegations have caused him significant pain, and he will be seeking full redress, legally and publicly. West Ham United's fans will be watching the situation closely, hoping the club can emerge from this difficult period stronger. The club's statement confirmed Sullivan's resignation and denied any allegations related to West Ham United or its operations. The situation is complex, and the club will need to navigate it carefully to ensure the best possible outcome. Sullivan's legacy at West Ham United is significant, and his departure will be felt. However, the club must move forward, and Virani's leadership will be crucial in the coming weeks and months. West Ham United's future is uncertain, but one thing is clear - the club will continue to fight for success on and off the pitch.
