Andy Harsley will try to persuade the Dragons to invest in his Alma Park-based firm which has developed and manufactured the Rapstrap.

The Rapstrap is what Andy describes as "the next generation of cable tie".

They can be used to fasten almost anything, are strong, durable and re-useable and come in a huge selection of sizes and colours.

The 35-year-old, who was invited to Pinewood Studios to film the show, is refusing to reveal whether he is successful in the Den.

He said: "I'm not allowed to say anything about what happens - you'll just have to watch.

"It was my friend's idea to go on to the show and if you get an opportunity to go before the Dragons you can't say no.

"I'm more concerned about being shown on television as I have no editorial control and I've got no idea what they're going to show."

Andy and his family and friends will be watching the show, which airs at 9pm, in the Blue Pig in Swinegate, Grantham.
