Dundee United have parted company with manager Jackie McNamara in the wake of Saturday's 2-1 defeat to St Johnstone at McDiarmid Park.
The former Partick Thistle boss had been in charge since replacing Peter Houston in January 2013 and was the longest-serving manager in the Ladbrokes Premiership.
McNamara led United to both the Scottish Cup and League Cup Final during his time at Tannadice but leaves with the team sitting 11th in the table, with five points from nine games ahead of this weekend's trip to bottom club Partick Thistle.
A club statement released on Monday night read: "Dundee United Football Club and Jackie McNamara have mutually agreed the departure of McNamara as first-team manager with immediate effect.
"Following widely-reported talks between the chairman and McNamara, the club and McNamara agreed that a change was required to improve the results of the club’s first team, with immediate change being required following the club’s start to the season.
"Simon Donnelly, Darren Jackson and Craig Hinchliffe have also left the club. The club thanks Messrs McNamara, Donnelly, Jackson and Hinchliffe for their service.
"The club will commence recruitment for a new first-team manager and associated staff."
