Delia Smith and Heston Blumenthal in Waitrose ads

Two of Britain's best-known chefs are pairing up for the latest Waitrose campaign.

TV favourite Delia Smith and molecular maestro Heston Blumenthal will star in the supermarket chain's ads for the next three years.

The pair are due to film a series of television adverts as well as appearing on billboards and in magazines.

Although the new deal is said to cost millions, it is reportedly no match to Jamie Oliver's contract with Sainsbury's.

"We're not spending obscene amounts on some celebrity to turn up and be in our adverts as others have done," says the commercial director of Waitrose.

"This is about two people who genuinely share our passion for food and who shop with us."
