Branston Pickle is to join the growing roll of big brands teaming up with Walkers crisps, with the launch of Branston Pickle and Cheese Walkers Crisps next month. News of the limited edition flavour follows the announcement of a Marmite version last week. Both brands will form part of a new Walkers range which has an essentially British theme to tie in with the Queen's Golden Jubilee Year. A spokesman refused to rule out further collaborations to cash in on Jubilee nostalgia. Heinz Tomato Ketchup became Walkers' first guest star flavour last year. {{P&P }}
