Daniel Kretinsky is set to become the largest shareholder at West Ham United – with David Sullivan also increasing his stake in the club.In a move that would deliver a major blow to Amanda Staveley, who had reached an initial agreement to buy the Gold family’s 25.1 per cent stake in the Championship outfit, Czech billionaire Kretinsky is thought to have exercised pre-emption rights.It means Kretinsky, along with the other existing shareholders, will instead split the Golds’ holding, leaving former Newcastle United director Staveley in the cold.Terms of the deal are yet to be disclosed however, it is understood that, as a result, Royal Mail owner Kretinsky will up his stake from 27 to 46 per cent, with Sullivan – who stood down as joint-chairman in June in the wake of serious allegations that he abused his power by preying on women for sex – increasing his holding from 38.8 per cent to 40 per cent. American investor Tripp Smith would expand his share from 8 to 11 per cent, with the remaining shareholders rising from 1.1 to 3 per cent. Former West Ham joint-chairman David Sullivan is set to increase his stake in the clubSullivan, 77, ‘categorically’ denies the claims against him. He is banned from having one-to-one contact or direct access to the Hammers women’s and youth teams following a historical complaint to the FA. The Independent Football Regulator said it would seek ‘urgent information’ regarding the allegations from Sullivan, and also contacted Essex Police.West Ham have been contacted for comment. Staveley had offered £150m for the Gold stake, which some viewed as the first step towards a full takeover.
