Philip Newman-Hall has announced plans to retire as managing director of Belmond Le Manoir aux Quat'Saisons.
He previously worked as acting general manager at Stapleford Park in Leicestershire as well as general manager of Bovey Castle in Devon, a role he left after just six weeks in 2005.
Commenting on his decision to retire, Newman-Hall said: "I feel that the time is just right as I reach 60 and Le Manoir is in the midst of one of its busiest years to slow down and take things easier.
"There are still major projects for my successor to take on and exciting developments ahead. I am sure that Le Manoir will play a major role in the opening of Belmond Cadogan hotel in London."
Newman-Hall said he will retire from full time employment in September but will remain active in the hospitality industry.
He said: "It is not my intention to disappear completely. I wish to continue active involvement in some of my mentoring projects and the industry charities together with becoming more involved with the Worshipful Company of Innholders and The Master Innholders.
"I am also hoping that the odd advisory and consultancy roles will come my way."
A successor has yet to be appointed, but Newman-Hall indicated that negotiations are currently in progress.
Raymond Blanc described Newman-Hall as "a brilliant man" who he is going to miss enormously. "We have had an extraordinary, enriching, highly professional relationship - it has been the relationship of a great manager with that of a very creative man," said Blanc. "As the creative half, I know my limitations as a manager, and Philip has filled the managerial role in a highly effective and successful way in helping to drive the business forward."
