Neil Lennon is no longer Celtic manager after he tendered his resignation with his side 18 points off the top in the Scottish Premiership.
Assistant manager John Kennedy will take interim charge of the team.
Lennon started his second spell at the club in February 2019 when Brendan Rodgers left for Leicester City and led the club to two titles, two Scottish Cups and a League Cup.

We thank Neil sincerely for all he has done for the club and we wish him every success going forward.
However, Celtic are well behind their Glasgow rivals, Rangers in their bid to win 10-straight titles and slumped to an away defeat at struggling Ross County on Sunday.
Last season was called early amid the coronavirus pandemic, with Celtic handsomely ahead of Rangers and crowned champions, having also defeated their rivals in the League Cup showpiece.
But this term, as the club pursued an unprecedented 10th league title in succession, things unravelled spectacularly.
Celtic were eliminated from the second round of Champions League qualifiers at home by Ferencvaros and won just one of their six Europa League group games.
Although they won nine of their opening 10 league fixtures, they lost the first two Old Firm derbies of the term and dropped points to Aberdeen, Hibernian, St Johnstone and Livingston.
