Chesterfield have parted company with manager Martin Allen following yesterday’s heavy defeat at home to Solihull Moors.
The Spireites lost 4-0 on Boxing Day which saw them drop into the National League relegation zone following just four wins from 25 games.
Assistant-manager Adrian Whitbread and head of recruitment/goalkeeper coach Carl Muggleton have also left the club.
CEO Graham Bean said: “On behalf of the club, I would like to thank Martin and his staff for their hard work and wish them all the very best for the future. The search for a new manager is now underway.”
Academy manager John Pemberton will take charge of the team for Saturday’s game at home to Hartlepool United.
Allen’s departure comes just hours after director and company secretary Ashley Carson stepped down from the board of directors.
A statement read: “He listed his current workload outside the football club as a reason for his resignation with football club matters taking a considerable amount of his time recently, he wished to reduce his day to day involvement in the club.
“Carson will continue to remain as company secretary, attend board meetings and retain his 3% of shares within the company. His shareholding is the third largest after Dave Allen and Sue Roberts.
“He also confirmed that his director’s debenture would remain in place for now and that he would not be requesting the loan be repaid.”
Carson, who joined the board in March 2010 and was appointed as company secretary in February 2014, said: “I would like to thank the chairman, Mike Warner and fellow director John Croot for their support.”
