Dover have sacked manager Chris Kinnear.
Whites sit 23rd in the National League and have won just once this season in 14 games, picking up only seven points.
It brings to an end Kinnear's second spell in charge at Crabble, having taken charge again in January 2013. He was previously manager from 1985 to 1995.

A statement released by the club revealed that they asked Kinnear three weeks ago to provide a masterplan to turn the club's fortunes around.
But Kinnear's plans failed to "materialise in a satisfactory form" and he leaves Dover after a run of 10 games without a win - during which time they have only scored five times.
"Chris has been a big part of Dover’s success over recent years and the board recognise this," said a Dover Athletic club statement. "However, our current position and form is not something we can allow to continue.
"3 weeks ago at a meeting between the board and the Manager, Chris was asked to produce a written plan of what steps he would be taking and what support he needed from the board to rectifying our current situation, sadly this did not materialise in a satisfactory form and results have not improved.
"As a consequence, chairman Jim Parmenter today relieved Chris of his position."
Kinnear spoke to kmfm in his final interview as Dover manager
Dover chairman Jim Parmenter said: "This has been a really tough decision to take, I have worked with Chris for a long time, he has been highly successful with us, but football is changing.
"There has clearly been some poor player recruitment decisions taken during closed season, which is something we will be addressing.
"There are also a number of issues around training and our ways of working, which we will be looking at.
"We have a good setup at the club, a decent playing budget and supporters who want to be proud of their team.
"We need to move forward in a manner that gives us the best opportunity to progress – that means avoiding relegation as a minimum and ideally pushing on towards the other end of the table."
Assistant boss Jake Leberl has been put in charge for Saturday's home game with big-spending Salford.
Dover added they will be making an announcement early next week about the future direction of the playing team and football management team.
