Fajerson, a former executive at a number of property companies, served as a member of the audit committee for Green Gaming Group aside from his duties on the board.
“Owing to time constraints, he will step down from his post with immediate effect,” Mr Green said.
“Hans Fajerson will remain as the largest shareholder of Mr Green & Co with 20.2% of the votes.”
Mr Green has not confirmed whether it will be seeking to appoint another executive to replace Fajerson.
