Greggs scoffs at reports of snub by its Christmas ad star Nigella Lawson

TV chef, who has signed up for bakery chain's first ever festive advert, says she is a fan of its sausage rolls

Nigella Lawson has issued an impassioned paean to the Greggs sausage roll, amid reports of a banger-based dust-up that threatened to cast a shadow over her appearance in the bakery chain's first ever Christmas advert.

Greggs confirmed on Sunday that the celebrity chef and cookbook author had agreed to star in its inaugural Christmas promotion, in which Lawson will purr over such delicacies as vegan festive bakes.
