Exclusive Mary Carmichael Walkers has lined up savoury spread stalwart Marmite as its partner for another foray into dual branded crisps. The new product ­ Walkers Marmite flavour crisps ­ forms part of a big campaign of activity from the crisps giant which is believed to focus on the Queen's Golden Jubilee. It is also set to include another essentially British household name brand. Due for launch at the end of February as a 12-week limited edition, the Marmite variant follows last year's permanent addition ­ Heinz Tomato Ketchup flavour. It will be backed by TV commercials in April featuring Walkers' regular frontman Gary Lineker. These follow a £3m television commercial campaign celebrating Marmite's centenary and heritage. For Marmite's brand owner Unilever Bestfoods, the crisps offer an effective way to move the brand from the breakfast table. "Our strategy is to get into snacking, and this tie-up with the UK's biggest food brand is perfect," said group brand manager Oliver Bradley. {{NEWS }}
