Livingston have sacked the management team of Allan Preston and assistant Alan Kernaghan.
Allan Preston took over from former manager Davie Hay
Preston was promoted from first-team coach in June and brought in Kernaghan, who had been player-manager at Clyde.
He said: "Alan and I were relieved of our duties, but I cannot say too much because of confidentiality."
Club captain Stuart Lovell is also facing dismissal, having been critical of Preston after defeat by Aberdeen that leaves Livi bottom of the SPL.
BBC Sport understands that the midfielder, whose contract runs out at the end of the season, is to face a disciplinary committee either next week or the week after.
A dressing-room row had followed Saturday's 2-0 home loss, which was Livi's seventh successive defeat, and Lovell later raised doubts over the club's finances.
Preston said of his own departure: "It was a shock and I had no inkling that it was about to happen.
"I have already cleared my desk, although I wasn't told to do so within any particular time.
"Everyone at the club has been good to us. I am very disappointed obviously because it was a great place to work and it is a great club."
Preston had been installed as Livi manager instead of previous incumbent Davie Hay after Pearse Flynn's Lionheart Consortium took management control of the club.
The former Dundee United, Dunfermline Athletic and St Johnstone winger, who had management experience as Macclesfield assistant before moving to Almondvale, was given a two-year contract.
But Flynn said that results had not been good enough.
"Allan Preston has done an excellent job in often very difficult circumstances," he said.
"When Lionheart took over management of Livingston before the start of the new season, the club had only four players under contract.
"Allan responded with a great deal of hard work and enthusiasm and we were able to pull together a first-team squad very quickly at a time when the future of the club was less certain than it is today.
"Unfortunately, we have come to the decision to find another manager after reviewing the football operations and also the club's recent performances."
Reserve team coach Alex Clelland, the former Everton and Rangers defender who was previously assistant manager at East Stirlingshire, will take charge of the Livingston first team for Saturday's match against Kilmarnock at Rugby Park.
Lionheart said it will make a further statement about the manager's post early next week.
Kernaghan earlier this month rejected the opportunity to speak to Inverness Caledonian Thistle, who were announcing Craig Brewster as their new manager while Livi were dismissing their management team.
