This week's hub of invention sees prospective entrepreneurs/mentalists pitch yet business ideas, including a shoe-polish booth for the 21st century, a publishing venture, a range of protective covers for mobile phones and computer equipment, and a sausage-cooking accessory. A pianist presents a youthful take on classical music and tries to secure funding for his future recordings, while an inventor from Manchester returns with more crime-prevention products after failing to impress the panel in a previous series. Theo Paphitis, James Caan, Deborah Meaden, Peter Jones and Duncan Bannatyne decide where to invest their cash, with the usual side of snide. The last in the series of Taking The Flak can be seen at 10.00pm.
