David Sullivan has stepped down as West Ham chairman after 16 years at the club.The 77-year-old revealed last weekend he is at the centre of serious historic allegations with details of the allegations emerging on Monday.Sullivan has been West Ham’s largest single shareholder since the death of business partner David Gold in 2023RexEx-adult industry kingpin Sullivan has categorically denied the claims that made against him, while resigning from his role with the Hammers to focus on a legal defence.A joint investigation by the BBC and The Times says seven women have come forward, accusing him of abusing his power and sexually-exploitative behaviour.The allegations include claims that he pressured them into sex during business meetings, where he is accused of offering to boost their careers if they slept with him or gave him oral sex.One of the women claims she felt forced to have sex with Sullivan even though she did not want to.It is also claimed that Sullivan separately admitted paying for sex in the 1990s with a girl who, he says, he believed was 16 or 17 years old. Sullivan was in his 40s at the time.It only became illegal to pay for sex with a 16 or 17-year-old in 2003.A statement from West Ham read: “Mr Sullivan has also resigned as a director of both WH Holding Limited and West Ham United Football Club, having been made aware of the impending publication of serious historic allegations. It is understood none of the allegations relate to West Ham United or any of its operations.“Through his own legal representatives Mr Sullivan denies any illegal conduct and has taken the decision to step down in order to avoid disruption to the Club while he addresses the matter privately.“Interim Chief Executive Officer Karim Virani, reporting into the current Board of Directors, will continue to be responsible for leading the Club’s day-to-day operations. The Club will provide an update on the future structure of the Board of Directors in due course, but will make no further comment at this time.”David Sullivan statement in fullI have recently become aware that factually incorrect and entirely false, decades-old allegations concerning my personal life are due to be broadcast and published.The false allegations levelled against me have been sensationalised by the media. After a lifetime spent building businesses in the adult industry in which I have met thousands of women, it is sadly inevitable that a small number of improper conduct claims are being made against me. I categorically deny these claims.I am a private man, and those who personally and professionally know the real David Sullivan, not the caricature invented by the tabloids, know exactly who I am and what I stand for. I am absolutely not the person the media has decided to paint me as.I have not been provided with any proper explanation as to how these individuals or their claims were independently verified or assessed for credibility prior to publication. I believe that the entire process has been fundamentally unfair and completely lacking in any due impartiality. I will be suing the BBC for libel, along with any other media outlet that repeats any libelous allegations.None of these allegations relate to my more than 30 years in football; West Ham United has been one of the greatest passions and privileges of my life. I care deeply about the club, its supporters, its players, its staff, and its future. At what is already a challenging and important time for the club, I refuse to allow personal matters concerning me to become an unnecessary distraction or a source of instability.Therefore, after very careful consideration and with a heavy heart, I have decided to resign as Joint-Chair and Director of West Ham United FC with immediate effect.This has been an incredibly painful decision to make, but it is one made out of love, respect, and responsibility toward a football club and a fan base that deserve absolute unity and focus moving forward.I am stepping down to apply my full energy and attention on fighting these false allegations. I have officially engaged my legal team and we are preparing to issue legal proceedings in respect of each and every false complaint that has been made against me. I will be seeking full redress, legally and publicly, on every single front.As I depart, I want to thank everyone connected with West Ham United, past and present, for the loyalty, friendship, memories and European adventures and successes that I will carry with me forever. West Ham United will always remain close to my heart, and I have total confidence that the Board of Directors and interim Chief Executive Officer Karim Virani will do everything they can to take the club forward in the right direction. I wish everyone connected with the club every success in the future.I will not be making further public comment at this stage, but I reserve all legal rights available to me in relation to any false or defamatory allegations.The London Stadium will play host to Championship football next seasonGettyIt has been suggested that co-owner David Kretinski and co-chair Vanessa Gold will now run the club, with Sullivan’s son Jack to have some involvement.Karren Brady stepped down from her role as vice-chair in April, ending a business relationship with Sullivan which began three decades ago.Alongside the late David Gold, Brady and Sullivan ran Birmingham City between 1993 and 2009, before the trio launched a takeover of West Ham in 2010. The Hammers were relegated from the Premier League to the Championship at the end of the 2025/26 season. They recently announced that Nuno Espirito Santo will remain as manager despite widespread reports he was set to leave. talkSPORT understands Kretinsky, the club’s second-largest shareholder, pushed for Nuno to stay, while Sullivan was more inclined to change.
