The June documentary, Don't Blame the Council, led some viewers to suggest ITV's portrayal of council workers as lazy and the council itself as ineffective was deliberately negative, while others questioned the council's decision to let the documentary go ahead.
In July, the council suspended head of PR Chris Dunbar and launched an investigation into the film. Terry Dunn, the director of environment whose oversight of bin collections featured prominently in the programme, was also reported by Wigan Today to have been suspended – although a spokeswoman for the council said at the time she could not comment on
A new statement from Lord Peter Smith, leader of the council, reveals Dunn has now resigned.
Smith said: "Wigan Council can confirm that it has received and accepted the resignation of Mr Terry Dunn, the director of environmental services at Wigan Council. The council will make no further statement in the interests of preserving the integrity of the investigation concerning other employees, which will continue."
Wigan Today also reports that Dunbar remains suspended. His LinkedIn profile still lists him as the council's head of PR.
