Thanet DC chief executive Sue McGonigal has resigned after spending six months on sick leave.
Ms McGonigal was the subject of a £47,000 probe by a barrister into allegations that she had a conflict of interest in a planning matter, which in October exonerated her from blame.
Green party councillor Ian Driver had alleged that the conflict arose as the chief executive was a board member of regeneration body East Kent Opportunities, which voted to appeal against a decision by Thanet’s planners.
Ms McGonigal went on sick leave in June but the council said last month that councillors, “have given their support for Sue to return to work once she recovers”.
A council statement said that following Ms McGonigal’s departure, Thanet was “looking to undertake the appropriate plans to recruit to this post”.
Madeline Homer will continue as acting chief executive.
