AN Oxfordshire teenager could be behind a surge in global carrot sales after setting up a page on Facebook urging people to "panic buy" the vegetable.

Supermarkets are bracing themselves after more than 230,000 people joined Freya Valentine's group.

It urges people to "go out and buy a load of carrots" on her birthday, which was yesterday.

Ms Valentine, 19, from Goring, said the interest highlighted the power of social networking sites.
