It is the first time Warburtons, the second biggest grocery brand in the country after Coca-Cola, has expanded into the snacks category.
Its new ranges, which launch on 15 March, will be called ChippidyDooDaa pitta chips and SnackaDoodle wholegrain snacks, with both available in a variety of flavours.
Warburtons plans to treat the two new products as standalone brands, with two dedicated websites showcasing the product range and endorsed by the Warburtons brand logo.
Clarion has been the retained national consumer PR agency for Warburtons since 1999, and is also involved with campaigns surrounding both Warburtons new sponsorship of ITV's Coronation Street and National Bread Week in May.
Clarion MD Amanda Meyrick said: ‘Moving into the snacking category is an exciting new step for both Warburtons and us, and we'll be pushing the message that these two new ranges are innovative, high-quality snacks that offer the consumer a tasty alternative to crisps.'
