Three top Debenhams directors including chief executive Rob Templeman will make a paper profit of more than £100m if the retailer pushes ahead with its floatation. Debenhams owners will make a £1.8bn return less than two and a half years after they bought the business. Rival private equity firms have been approached in the past few weeks to test their interest in assembling a buyout of the company. Debenhams private equity owners plan to sell a 60 per cent stake according to a research note circulated to fund managers by Citigroup, one of the two banks leading the float.
