Sacked ABC managing director Michelle Guthrie was rated so poorly by her senior colleagues and board directors that she ranked in the bottom 4 per cent of chief executives for integrity.

She was also judged to be "arrogant", "autocratic" and "distant" in a performance review that concerned the board so much they arranged for board director Donny Walford to intervene.

Ms Guthrie's "extremely poor" performance as ABC managing director was detailed in a submission to a Senate inquiry by former ABC chairman Justin Milne published on Thursday night.

According to Mr Milne, Ms Guthrie was required by the ABC board to undertake a 360 review in March and April this year, which was completed by directors and members of the ABC's leadership team who reported directly to Ms Guthrie.
