Comedy duo French and Saunders led the two teams

In teams of two, they sold off bric-a-brac as they vied for the Car Booty crown in Battersea, south London.

Celebs included comedy duo Dawn French and Jennifer Saunders and green-fingered stars Charlie Dimmock and Alan Titchmarsh.

Organisers are urging the public to hold their own car boot sales and raise money for Comic Relief.

Also taking part were property gurus Kirstie Allsopp and Phil Spencer, TV's queens of clean Kim and Aggie, and singer Jason Donovan and TV presenter Mariella Frostrup.

Among the items on sale were signed books and pictures, clothes, handbags, hats, and perfumes and cosmetics.

A Comic Relief spokesman said: "We hope that today's event will inspire the public to start fundraising for Red Nose Day on March 16."
