Monckton Leaves Post: Rosa Monckton, chief executive for the U.K. operations of Asprey & Garrard, will leave her post this week and become a consultant to the company, the firm said Saturday. Monckton, a former Tiffany executive, will assume the role of non-executive chairman of Asprey London Ltd. and Garrard & Co. Ltd., both U.K. operations of the parent Asprey & Garrard Group. Monckton was said to be earning a huge salary and used a helicopter to commute to work in London from her home in East Sussex. She is chairman of the Diana Princess of Wales Fountain Committee and of KIDS, a charity for disabled children. Asprey & Garrard will become two separate brands in April. Monckton will not be replaced. Her duties will be split between Gianluca Brozzetti, ceo, Asprey & Garrard Group, and marketing directors and showroom managers.
