Tommy Widdrington has left Kings Lynn. He told the club of his decision after this afternoon's 1-0 victory ove Chorley.
He had a contract until the end of next season.
"The club are disappointed to have been told by our manager Tommy Widdrington this evening that he is resigning in order to take up an alternative post at another club.
"Tommy is under contract with us, and the club in question have not contacted us to reach an agreement and nor has Tommy sought to reach an agreement that would allow us to waive the contractual position.
"We very much hope a swift resolution will be reached, as an alternative to a legal process.
"Meanwhile, given Tommy has made it clear that he has resigned with immediate effect (irrespective of his contractual obligations to the club) the search for a new manager begins now.
"We would not stand in the way of a manager (or player) who wished to progress to a higher level and has the opportunity to do so, but such matters need to be dealt with professionally and legally."
Update Sunday 2pm:
Widdrington is the new Aldershot manager.
