Originally ousted in March subsequent to a decision by shareholders, Morgan, who is also the grandson of company founder H.F.S. Morgan, took on an ambassadorial role, promoting the brand and selling the company’s unique sports car range worldwide.
Now, according to a statement from the car maker, Morgan "is no longer involved in the running of the business" but "remains a shareholder".
"The Morgan family recognises the management contribution that Charles has made to the family business as Strategy Director," the statement said, "However, to ensure continuing success, Morgan must look to strengthen and review its strategies, and acknowledges that our management team are better placed to steer the company in the future."
Morgan told UK publication Autocar that he is appealing the decision, saying, "As a family member I think I should have been consulted about this press release because it suggests that it comes from all of the family shareholders."
The Morgan family remain 100 per cent shareholders of the business.
The prized hand-built Morgan sports car range has consistently been in demand and expects it will build 1150 cars this year, up from 1122 in 2012.
