Charlton Athletic's majority shareholder Tahnoon Nimer has resigned as a director of the Championship club.
Addicks chairman Matt Southall confirmed they had accepted the Abu Dhabi-based businessman's resignation after his position became "untenable".
On Monday, Nimer and Southall both issued claims about each other's professional conduct.
Nimer was part of the consortium which completed its takeover from former owner Roland Duchatelet in January.
The boardroom dispute spilled out to social media on Monday with Syrian businessman Nimer posting a series of claims on his Instagram account about why he was withdrawing his investment in Charlton.
Nimer later deleted the posts before Southall issued a lengthy club statement stating Nimer had failed to invest "a single penny of the promised funds" since January and had also failed to pass the English Football League's Owners and Directors' Test.
Charlton are currently third from bottom in the Championship, two points adrift of safety and on a run of three successive defeats.
