Dragon’s Den is gearing up for the arrival of some new blood set to shake up the hit BBC show. A new dragon is set to enter the den in the form of 28-year-old Steven Bartlett who show bosses insist will encourage a "new generation of entrepreneurs" to apply for the format.The Manchester-born millionaire will replace Tej Lavani and join Peter Jones, Deborah Meaden, Touker Suleyman and Sara Davies in a move that makes him the youngest ever dragon to bring his money to the den.
