The festive tradition of the Marks and Spencer Christmas ad campaign is sprinkled with British celebrities this season, as it tries to capture cash-strapped shoppers.

This year's ads will be narrated by national treasure Joanna Lumley, and feature other favourites such as Wallace and Gromit, Stephen Fry and Strictly Come Dancing star John Sergeant, as well as regulars Twiggy, Myleene Klass and Noémie Lenoir.
