He says he will be pursuing other business interests.
Finegold founded the company in 1994, and he has been a non-executive director of Kensington since the company floated on the London Stock Exchange four years ago.
Kensington Chairman Peter Birch says: “He has made a very significant contribution in building Kensington into the successful company that it is today.”
Finegold says: “Kensington is a great company and it has been a privilege to work there. It has grown very strongly and has significant potential for further growth as it continues to benefit from operating in a dynamic and specialist market. As a committed long term stakeholder, I am looking forward to its future success.”
