Danny Wilson has resigned as manager of League One Swindon.
Wilson led the Wiltshire side to the play-off final last season - but a run of three points from the last 33 available has left Swindon in the relegation zone this time around.
Wilson said: "After conversations with the chairman (Andrew Fitton), where the club's current performance and current league position were discussed in detail, it was agreed that offering to resign would allow the board an opportunity to appoint a new manager while there are still sufficient games left this season for the club to be able to pull clear of the relegation zone."
He added: "Maintaining League One status has to be the priority for everyone.
"Naturally, I am bitterly disappointed to be leaving Swindon, especially after last season's success, but I know football is a results-driven game, and unfortunately in the past two months the results have just not been good enough."
Fitton said: "Unfortunately this season we have not enjoyed the consistent playing success that we all anticipated and our current league position makes for uncomfortable reading.
"Therefore, following discussions with Danny during the last 24 hours, he offered to resign from his position, acknowledging that the appointment of a new manager should inject a fresh momentum that will pull the club out of the relegation zone.
"I cannot thank Danny enough for his contribution to the club's playing fortunes but more importantly for the very professional manner in which he has conducted himself over these discussions. He leaves The County Ground with his head held high.
"The club will be announcing a replacement for Danny within the next 24 hours. It will be a proven, senior manager whose prime responsibility will be to ensure our League One survival by the end of the season."
