Pep Clotet has resigned as Birmingham City manager.
The 43-year-old was due to step down at the end of the season, but a 10th match without a win brought his departure forward.
Birmingham are 17th in the Championship table, four points above the relegation zone with four matches to play.
Clotet did not speak to the media after the loss to the Swans and his exit was announced just after 11pm.
A Birmingham statement read: "Pep Clotet has this evening left his position as head coach. He was due to step down at the season's end but it was mutually agreed that he should relinquish the role immediately.
"The board would like to place on record its sincere thanks to Pep for his efforts during the past two years.
"We will be making no further comment at this time."
