SHE is said to be worth tens of millions of pounds, but Dragon's Den star Deborah Meaden, who lives in Somerset, has revealed she loves browsing in charity shops for bargain priced second hand clothes.

She also told The Mirror that she only switches the heating on at home during a cold snap as a last resort.

Ms Meaden, aged 63, who is originally from Taunton, told the newspaper: "I buy second hand clothes.

"People do double-takes when they see me in charity shops.

"Now, everybody in the Den talks about sustainability, which pleases me."

She added: "I only switched our heating on in mid-December because it was -5C.

"We held out for a long time. I'm an absolute nightmare.

"I go around switching all the lights off."

Ms Meaden, who lives with her husband Paul in their Somerset mansion, acquired Wellington-based woollen cloth manufacturers Fox Brothers Ltd with fellow shareholder Douglas Cordeaux in 2009.
