TRADING standards chiefs in North Yorkshire are warning people not to respond to the latest chain letter circulating in the county.

The letter, which purports to originate in Norfolk, urges the recipient to earn £40,000 in cash by sending a gift of £10 to the top name on a list of six and then copying the letter 200 times randomly to chosen individuals.

Recipients are then told to delete the first name on the list and replace it with their own. The letter should progress down a pyramid-shape network of distribution.

However, the county council's trading standards service insists that if something seems too good to be true, it inevitably is.

Councillor John Dennis, executive member for trading standards, said: "These schemes rely upon a pool of new investors to keep coming into them, which will not happen.

"We would advise anybody who has received these letters to put them in the bin."
