Fashion entrepreneur Shami Ahmed yesterday pledged to continue his fight for control of men's wear retailer Moss Bros, despite new doubts about his ability to fund the bid. Yesterday it emerged that the retail entrepreneur owns just 0.4 per cent of Moss Bross shares, valuing his investment at only £121,594. Instead most of his 5.42 per cent interest in Moss Bros has been built up through a leveraged derivative called Contracts for Difference, or CFDs.
