The board of Carlisle United Football Club have decided to make a change and Steven Pressley will leave the club with immediate effect.
Chairman Andrew Jenkins said: “Steven has given his all and has worked tirelessly since the day he joined us.
“We understand the challenges and have supported him throughout, but we haven’t seen the evidence of progress we expected or needed to see.
“This is not something we can allow to continue, so sadly it is time to change, move on and look forward.
“I want to say a personal thank you to Steven, he has been a pleasure to work with and this has not been an easy decision for us to make.
“He leaves with our very best wishes.”
The existing coaching staff will take charge of football matters in the short-term.
There will be no further comment at this stage.
