Daniel Kretinsky’s West Ham plan as David Sullivan steps down as co-chairman

West Ham are facing one of the most significant boardroom shake-ups in their recent history after the club confirmed David Sullivan has stepped down from his role as joint-chairman.

The announcement arrived amid what the Hammers described as the impending publication of serious historic allegations against Sullivan.

The club stressed that the allegations do not relate to West Ham or its operations, while Sullivan has strongly denied any wrongdoing and says he intends to contest the claims through legal channels.

Interim chief executive Karim Virani will continue overseeing the club’s day-to-day operations and reporting to the board.

Sullivan’s departure marks the end of a hugely controversial era at the London Stadium.

Having helped lead the takeover of West Ham alongside the late David Gold in 2010, Sullivan oversaw some of the most headline-grabbing moments in the club’s modern history — good and notably bad.

During his tenure, the Hammers moved from Upton Park to the London Stadium, qualified for European competition on multiple occasions and lifted the UEFA Europa Conference League trophy in 2023.

At the same time, his leadership often divided opinion among supporters.

Many fans criticised transfer decisions, recruitment strategy and the move away from the club’s historic home, while protests against the ownership became a regular feature during difficult periods.

Even before this week’s developments, West Ham’s boardroom had already undergone major changes following the departure of vice-chair Karren Brady earlier this year.

Attention is now turning towards what comes next.

Daniel Kretinsky ‘readying move to take charge at West Ham’ after Sullivan exit

According to journalist Graeme Bailey, shareholder Daniel Křetínský is preparing to assume a leadership role at the club following Sullivan’s exit.

Kretinsky has steadily increased his influence at West Ham since purchasing a significant minority stake in 2021.

The Czech billionaire has long been viewed as a potential future controlling figure at the club, and reports throughout 2026 have suggested his role behind the scenes has become increasingly important.

Bailey’s latest update suggests those expectations may soon become reality.

The 50-year-old businessman has already played a key role in several major decisions at board level in recent months, reportedly including discussions surrounding manager Nuno Espírito Santo’s future following West Ham’s relegation from the Premier League.

Reports previously indicated Kretinsky was influential in the decision to keep faith with the Portuguese coach as the club prepares for life in the Championship.

That continuity could prove important.

West Ham face a crucial summer both on and off the pitch.

The club are attempting to rebuild following relegation, while several senior players continue to attract transfer interest.

Reports in recent weeks have linked Jarrod Bowen, Crysencio Summerville and Mateus Fernandes with potential moves away as the club seeks to reshape its squad and finances.

More players could quit the club, with West Ham braced for offers as French sides take an interest in promising young midfielder Mohamadou Kante.

Against that backdrop, stability in the boardroom will be viewed as essential.

Kretinsky has previously spoken of his long-term commitment to West Ham and has gradually increased his presence within the club’s decision-making structure.

While no formal announcement regarding a new chairman has yet been made, Bailey’s report suggests preparations are already underway for a significant transfer of power.

For West Ham supporters, the coming weeks could bring major change.
