THE success of Scunthorpe Dragon-slayer Sharon Wright has led to a complaint to the BBC.

Last month Ms Wright stunned the judges on Dragons’ Den when she pitched on the programme for investment in her business.

The 39-year-old single mum has invented a device called MagnaMole to thread cables through cavity walls.

And the Dragons, who are known for grilling hopeful entrepreneurs and giving some dismissive comments, all wanted to invest.

Since then Ms Wright has been inundated with enquires from around the world.

But a production worker from a company in Wales was less positive.

Super Rod Ltd, based in Gwent, also offers products to route cables and one of its workers is Brian Thomas.

He said they had been producing similar products for years and that as a TV licence payer he was angry he was helping to fund a corporation which advertised a rival product to that of his own company.

In a strongly-worded letter to the BBC, he said: "As a licence payer, I am funding your organisation, thus making me a stakeholder.

"As a stakeholder, please explain why I should compulsorily pay towards a corporation that advertises a threat to my own employment?"

It continued: "I cannot understand how your researchers failed to recognise the competition in the market place, thus permitting your broadcast. These are the views of a hardworking family man who does not want to see his employment jeopardised."

Ms Wright said she was sure Super Rod managing director Malcolm Duncan was a very busy man with a great product. She added: "All respect to him, he has done extremely well.

"It does not take me away from my drive and passion and I will continue to ride the road on the positive journey. I have a patent on my product so it cannot be the same product."

Ms Wright said: "The clever part about mine is the tapered screw cap with the magnet on the end, so it has the facility to align both magnets at whatever angle you are trying to thread the cable."

She said she had thousands of e-mails from all round the world since the programme and is this week moving to bigger offices within the Queensway Business Centre in Scunthorpe to cope with demand.

Ms Wright said: "I’m working 16 hours a day, seven days a week.

"But I’m loving it. I’m going to try and put all the enquires to bed."

Later Mr Duncan told the Telegraph: "I think what should be celebrated here is that you have got two good UK-based companies that are designing innovative products. We offer slightly different solutions for carrying out similar tasks. The good news is all the tradesmen out there have a choice."

Mr Duncan added: "We have no beef with Sharon whatsoever. Let’s look forward to both companies being successful."

The BBC has taken the view that the programme was produced well within the relevant guidelines.
