McGuire, who is due to exit the AFL club's board at the end of this year, has been under fire since the release of a damning report that uncovered a culture of systemic racism at the Magpies.

The long-serving president declared the release of the Do Better report, which came after it was leaked to the media, as a "proud and historic day" for Collingwood during a botched press conference.

The next day at the club's annual general meeting, McGuire apologised for how he described the findings of the club-commissioned independent review.

But backing down from his initial statements has done nothing to calm talk over McGuire's future at Collingwood, after more than 22 years in charge.

More than 70 people, including federal politicians Lidia Thorpe (Greens), Peter Khalil and Anne Aly (both Labor), have signed an open letter calling for McGuire's resignation.
