Paul Jewell has left his role as Ipswich Town manager by mutual consent, the Championship club announced on their official website.
Jewell had indicated that he could resign after the East Anglian side lost at Hull on Saturday, and lasted only one more game - a late 2-1 home defeat to Derby on Tuesday - before leaving his post.
His departure comes with Town at the bottom of the Championship table with only seven points and on a run of seven defeats in ten games.
He had been in charge at Portman Road since the start of 2011, and left following talks with owner Marcus Evans and chief executive Simon Clegg on Wednesday.
"Since he first walked through the door here, no one has worked harder to bring success to this football club than Paul Jewell," Evans told the club's official website.
"Unfortunately, his outstanding commitment has not been rewarded by results on the pitch and, having spoken with Paul at length, we feel it's best for him and the club if we go our separate ways."
Evans said he was "bitterly disappointed" by the development and added: "I would like to put on record my thanks for his services to the club and wish him every success in the future."
Former Wigan, Derby and Bradford manager Jewell said he had enjoyed working with both Evans and Clegg during his time in Suffolk, but acknowledged: "We all know that football is a results business, and I've never hidden from the fact that our results have not been good enough.
"It's been a privilege to be manager of such a fantastic football club, and I want to thank the staff and the supporters for the backing they have given me in my time at the club and wish Ipswich Town the best of fortunes ahead."
Clegg said Town's search for a successor to Jewell was "well under way" and that Jewell's assistant, Chris Hutchings, would be stepping in as caretaker manager until an appointment was made.
