The flavours are the most popular in different regions across the UK – Smoky Bacon (The Midlands), Pickled Onion (Scotland), Worcester Sauce (South East), Beef & Onion (Wales), Tomato Ketchup (The North) and Marmite (South West).

The packs include an on-pack promotion offering consumers the chance to win £5,000 every week when all six flavours are purchased, supported by a TV and digital advertising campaign launching in September.

Rachel Holms, senior marketing director at brand owner PepsiCo, said: “We all know that flavours like Cheese & Onion, Salt & Vinegar and Ready Salted are firm favourites with our Walkers’ faithful. What people do not necessarily know is that flavours such as Marmite and Smoky Bacon have just as much of a loyal following as some of our lead flavours within certain regions of the UK.

“Walkers has continually catered for the quirky and diverse tastes of the public and this has led to the development of some nationally popular, and surprisingly delicious, flavours that have become staples in most households. This campaign gives us the chance to highlight just how diverse our crisps range is and allows people to try flavours that they may not have come across before.”
