HOW THE ABC LEADERSHIP CRISIS UNFOLDED:
Monday, September 24:
* ABC managing director Michelle Guthrie is sacked by the broadcaster's board, who claimed it was "not in the best interests" of the broadcaster for her to continue in the role. She was halfway through a five-year contract.
* ABC chairman Justin Milne says Ms Guthrie's relationship with the government was a factor, but there had been no government pressure.
* David Anderson, a 30-year ABC veteran, is appointed acting managing director while a formal search for a replacement begins.
* Ms Guthrie says she is considering her legal options.
Tuesday, September 25:
* Both sides of politics say they expect more will be revealed about Ms Guthrie's sacking, with Labor eager to probe at Senate estimates.
Wednesday, September 26:
* A report emerges alleging Mr Milne had told Ms Guthrie to fire ABC chief economics correspondent Emma Alberici after former prime minister Malcolm Turnbull complained about her reporting.
* Communications Minister Mitch Fifield says his department secretary will run an inquiry into the matter and report as soon as possible. Labor and the Greens say they will pursue a Senate inquiry.
* A further report accuses Mr Milne of asking for ABC political editor Andrew Probyn to be fired. It is alleged Mr Milne told Ms Guthrie "you just have to shoot him".
Thursday, September 27:
* Pressure mounts on the chairman to resign, as both former prime minister Malcolm Turnbull and Communications Minister Mitch Fifield say they have never called for anyone at the ABC to be fired.
* The ABC board meets on Thursday morning without Mr Milne, before asking the chairman to step aside. He resigns.
