Ant and Dec join Jamie Oliver in Sainsbury's Christmas ad

LONDON - Mockney chef Jamie Oliver is joined by cheeky Geordie scamps Ant and Dec in this year's Sainsbury's Christmas ad.

After bumping (literally) into Ant and Dec in the supermarket Oliver notices that their trolley is full of pickled onions and pineapple chunks.

Taking pity on them he shows them a recipe for salmon, Stilton and cranberry toasted Ciabattas.

The downside is that he then stays at their party.

The ad, by Abbott Mead Vickers BBDO, broke earlier tonight.
