The former Newcastle defender was named as successor to Paul Simpson at Brunton Park in September following a short spell in charge of MK Dons. Despite having high hopes he could lift the Cumbrians out of the relegation zone and quell any fears over a possible drop into the National League, Williamson won just five of his 25 games in charge and a 5-1 home defeat against Swindon Town will now go down as the final game of his reign.

A club statement released on Monday morning read: “Carlisle United Football Club can confirm that head coach Mike Williamson has this morning been relieved of his duties and has left the club with immediate effect. Everyone at the club would like to thank Mike for his efforts during his time at the club. The club will give a further update in the coming days.”
