Spitfire Premium Kentish Ale will be rolled out in May in limited-edition celebration livery.

The packs - dubbed the ‘Bottle of Britain’ - carry Union Jack branding and a neck collar sporting the motto: ‘Keep Calm and Celebrate’.

Brand owner Shepherd Neame said the bottle had been developed to meet the need for products for the Jubilee, Olympics and Euro 2012.

“Retailers need event-focused products for a range of opportunities,” said brand manager Kate Maclean.
