Cork City FC and first team manager Tommy Dunne have parted company with immediate effect.
Dunne, who led the club back to the Premier Division in 2011, guided City to a mid-table finish last season, with the club currently sitting in seventh position in the Premier Division table.
Stuart Ashton will take over the role of caretaker first team manager "on a week-to-week basis".
Ashton, who first joined the club as a professional in the 1984 season, has won every honour open to Cork City FC underage teams, most recently retaining the Under 19 National League and Cup double.
"The board have not come to this decision lightly or hastily, and we are extremely grateful to Tommy for all he has done for us over the last few years," said Cork City FC chairman Mick Ring.
"We will always remember his time here fondly and wish him the very best for the future, but we feel our decision is in the best interests of the club.
"We must now look forward to our upcoming FAI Cup game against Kilbarrack and mid-season friendly against West Brom."
