Sara Davies, Touker Suleyman, Deborah Meaden, Tej Lalvani and Peter Jones cast their eyes over the final batch of business pitches of the current series. Stepping into the arena are an inventor who has come up with an unusual way of controlling household draughts, a businessman who claims there is money to be made in encouraging dogs to eat bugs, a fitness teacher who launches into a shimmying session, and the creator of a high-end garment bag. Evan Davis oversees proceedings as the Dragons decide if any of these pitches are worthy of investment.
