Walker's Snacks is throwing its energy behind an on-pack tie-up with Comic Relief and the start of a £7m round of support for Doritos. New comic ads, featuring a host of celebrities, hit TV screens this week in a bid to push sales and raise £1m for Red Nose Day through new Baked Bean flavour crisps.

The support for Doritos, meanwhile, will kick off with a £1m TV advertising campaign in April to back next month’s launch of new Extreme Chilli Heatwave flavour.
