Stuart McCall has resigned from his role as Motherwell manager after failing to end the team's dismal run of form in the Scottish Premiership.
Despite enjoying success in recent years, including a trio of top-three finishes in the top tier of Scottish football, McCall has elected to leave Fir Park after Motherwell stretched their losing record to five games with a 2-1 defeat to St Johnstone on Friday night.
A club statement read: "Everyone at Motherwell FC would like to sincerely thank Stuart for his contribution to the club, which will go down as one of the most successful managerial tenures in our 128-year history.
"We have been acutely aware of results this season, but everyone at Fir Park was confident in his, and the team's, ability to turn things around.
"However, following a long conversation this afternoon, Stuart felt it better for all concerned if he stepped down with immediate effect and we respect that."
Assistant manager Kenny Black will take charge of the team while the club begin the search for McCall's replacement.
