Gary Locke resigns as Kilmarnock boss after home loss to Hamilton
The Ayrshire side are second bottom of the Premiership table after Saturday's 1-0 defeat.
Gary Locke has resigned as Kilmarnock manager following the club's 1-0 loss to Hamilton Accies.
The former Hearts coach, who replaced Allan Johnston in February 2015, has quit with the club second bottom of the Premiership table with six wins from 25 league matches.
Locke has come under pressure following poor results with Dundee, Ross County, Partick Thistle, Aberdeen and Dundee United scoring four or more goals in a single game against Killie this term.
Kilmarnock have won three of their 13 home Premiership fixtures and occupy the relegation play-off spot in the top flight with 24 points from 25 matches.
Locke was handed a three-year contract in April and appointed Lee McCulloch and Peter Leven to his coaching team this summer.
Kilmarnock face Rangers at Ibrox in the Scottish Cup fifth round next Saturday.
A club statement confirming Locke's departure said: "[Lee] McCulloch will be assisted by Peter Leven and under-20 head coach Alan Robertson.
"The board of directors would like to thank Gary for his time with the club and wish him every success in the future.
"Lee McCulloch is the holder of a UEFA Pro Licence and has been acting as a first-team coach this season, although he remains registered as a player."
