Walkers has lined up Jenson Button, Frank Lampard, JLS and Marco Pierre White as part of a meal deal campaign to target people who don't eat crisps with lunchtime sandwiches.

The celebrities made guest appearances in the town of Sandwich, Kent, from 3-5 March to launch a campaign culminating in television and digital advertising.

Walkers featured heavily in meal deals last year and helped it outperform the category ('Meal deals driving impulse sales revival', 16 January).
