After selling the business in 1991, he became Chief Executive of the Granada Group, master minding the company's takeover of the Forte Group - still the biggest hostile takeover bid in British commercial history. He then became Chairman of Citigate, one of the UK's most respected financial PR companies. He was Chief Executive of Conran for seven years, leaving in 2013 to concentrate on writing and photography. As an art photographer, his work has been exhibited in London, Paris, Brussels, Ghent and Amsterdam. He is also a trustee of The Photographers' Gallery.
