Dragons’ Den BBC1, 8pm

The Apprentice isn’t the only business-themed series making a welcome return to our screens tonight. Peter Jones, Deborah Meaden, Touker Suleyman and Sara Davies are also back in their Den, and they are joined by new recruit, marketing supremo Steven Bartlett, who, at 29, is the youngest Dragon to date. Will he show much youthful enthusiasm for the ideas being pitched to him?
