To celebrate the launch of ­Walkers Baked, the number one crisp brand, Walkers is offering retailers the chance to win one of five three-case Walkers Baked stackers and a case of each ­Walkers Baked flavour - Cheese & Onion, Ready Salted and Salt & Vinegar.

New Walkers Baked contains 70% less fat than regular crisps and, with a controlled portion size of 25g, contains less than 100 calories per pack - all with a great new Baked taste.

Walkers Baked is designed to appeal to people who love crisps and are looking for a low-fat alternative that doesn't compromise on taste. The launch will be backed by a £6m marketing support programme.
