Chief Executive Nigel Clibbens said in a statement on the club's website: “We have decided to make this change after very careful deliberation.
“It is made with the long term interests of the club in mind. It signals a change of direction by the club and a new approach.
“Chris worked to represent Huddersfield Town to the best of his ability; to develop us, improve us and take us forward. He now leaves us well placed for the future challenges ahead.
“With his skills and qualities as a person, it won’t be too long before Chris finds a new challenge and we wish him success when that comes.
“We would like to thank Chris and Alex and give them our best wishes for the future.”
