Duncan Bannatyne, Deborah Meaden, Richard Farleigh, Peter Jones and Theo Paphitis have all built up their own fortunes from scratch and are now ready to back the best ideas and inventions brought into the Den with their own cash – but will any survive the experience?

Other pitches this week include: a colourful new take on the rocking horse; a web-based contract car lease hire company with an eye-catching line in advertising; a hi-tech service for diagnosing and solving problems with feet; and a new laundry and travel storage range.
