So for all you wannabe inventors and entrepeneurs here are the things the millionaires are looking for:

"All we want is two simple things," Theo explained.

"First, for someone to come up with a good idea and to have done their homework. And also, to show that they're capable of managing their business. That's it.

"If they can do those simple things, they've got a hell of a chance of getting out of there with some cash."

Theo also admitted ot the Manchester Evening News that he was looking forward to working with his fellow Dragons again: "We all fit into the show reasonably well," he says.

"Although there's always friction when you try to invest, that's the nature of the show. I make my decisions based on very simple criteria - do I like the person, and secondly, is the idea good? If those two work, I'm in."

So there's what the millionaires are looking for......anybody willing to give it a go?
