The treatment of Don Revie by the Football Association made him the first victim of "cancel culture", according to an MP.
Chris Evans wants an apology from the FA for banning Revie from football for 10 years.
Revie left the England job for a post overseas.
The MP said Revie was the greatest manager this country has ever seen, and the fans supported his campaign.
During the 1960's and 70's, Leeds United had enjoyed big successes and equally disappointing ones.
The FA charged Revie with bringing the game into disrepute after he left his job as England manager.
Revie never worked in England again after the ban was overturned.
The manager was the first victim of cancel culture according to Mr Evans, who wrote a biography of Revie.
He wants an apology for Don's surviving family. Don was banned from the game for 10 years, which hurt his reputation.
He did nothing wrong. I believe the FA launched a witch hunt.
Kim Revie, the daughter of the manager, supported his campaign and a petition was launched.
Revie won six England caps while he was a player and he played for many clubs.
He was the manager of the team when it became one of the top English teams in the 1960s and 70s.
In 1969 and 1974, the league and cup were won by Leeds United.
Revie's methods were controversial and outside the city the team gained the nickname "Dirty Leeds" through its uncompromising style.
The manager of the club was portrayed in the film The Damned United, which dramatised events at the club when Brian Clough took over from Revie for 44 days in 1974.
Revie died of motor neurone disease in 1989.
The Football Association has been contacted.
