IAN Holloway has been sacked by Millwall.
Lions chairman John Berylson has brought Holloway's disastrous tenure at The Den to an end in the wake of a 4-1 home defeat to Norwich on Saturday.
Neil Harris has been placed in caretaker charge until the end of the season.
Berylson, who publicly backed Holloway on several occasions in recent weeks, came to the decision over the weekend and was supported unanimously by the board.
The club's American owner had been reluctant to pay the termination clause in Holloway's contract but the limp display against the Canaries has seen him lose patience.
He said in a statement: "This was a hard decision to take because we very much hoped that Ollie would prove to be the man to take us forward and on to the next level.
"I would like to thank him for his efforts, and in particular for keeping us in the Championship last May.
"This season, though, has proved to be an extremely challenging one and we now find ourselves facing another uphill battle to avoid relegation.
"Ian Holloway remains a fine manager and it was his impressive track record which led us to appoint him some 14 months ago.
"However, our view is that the decision to part company at this stage is in the best interests of the football club going forward.
"Neil Harris has agreed to take over managerial duties for the remainder of the season and I am confident that Millwall fans will give him every support over the next couple of months as we strive to turn our current run of form around."
Millwall are second from bottom in the Championship, eight points adrift of safety and on their worst-ever run of form at The Den in a single league season.
Since September 1, Holloway has overseen just four wins from 33 fixtures and the Lions are on the brink of relegation to League One.
