Scott Duxbury has resigned as West Ham United chief executive.
The move comes as a result of this month's takeover of the club by David Gold and David Sullivan, with Duxbury effectively being squeezed out when the owners brought in their former Birmingham colleague Karren Brady as vice-chairman.
"I am proud of my work at West Ham United, but feel the time is right for me to pursue other opportunities," said Duxbury in a statement. "I wish Mr Sullivan, Mr Gold and Karren great success in driving this wonderful football club forward, and I know under their stewardship the club will prosper. Thank you to all the supporters who have kept faith with the club through good and bad times."
