DRAGON’S DEN star Theo Paphitis has walked out on lingerie chain La Senza after a bust-up with its private equity owner, Lion Capital. It is thought Paphitis quit the board after a clash of opinions over how the business should be run. The entrepreneur was in talks with Lion to buy a majority stake in the firm, after selling it for £100m in 2006, but now it is believed those negotiation have broken down.
