Czech businessman Daniel Kretinsky has completed his purchase of a 27 per cent stake in West Ham.
Kretinsky, who owns Czech club Sparta Prague, and his colleague Pavel Horsky have been appointed to the board at the London Stadium alongside joint-chairmen David Sullivan and David Gold and vice-chair Karren Brady.
Brady said: “On behalf of the board I am very pleased to welcome Daniel Kretinsky, Pavel Horsky and (investment group) 1890s holdings a.s to West Ham United.
“We are always looking to continue to progress and Daniel’s involvement brings investment which strengthens the club’s position, and in turn will assist in the development of the club’s key areas of focus.
“David Sullivan and David Gold have always been very open about finding the right investors to join them on the journey as custodians of West Ham United, and Daniel’s strong business acumen and football experience will be of huge benefit to the club.
“We very much look forward to working with him and Pavel.”
West Ham say the windfall will initially reduce the club’s debt and help continue the strides made on the pitch over the last couple years.
