Dunstable Town manager Darren Croft has resigned from the club.
The Blues, who are currently 12th in the Southern League Premier Division, have appointed Tony Fontanelle as caretaker boss until the end of the season.
Chairman John McLoughlin said: “Darren Croft has resigned as manager of Dunstable Town with immediate effect.
“I had hoped that Darren would remain as manager until the end of the season but he has declined this offer,
“I wish to thank Darren for his hard work and commitment and congratulate him on the success he has achieved for DTFC in recent reasons.
“I have plans for the club that will strive to strengthen and improve on the success that has already been achieved by Darren and Paul Reeves but firmly believe that the level the club is now requires new management to move us forward.
“I have appointed Tony Fontanelle as Caretaker Manager until the end of the season and will review the situation at that time.”
