Country Life has added a Union Jack to the gold foil of its butter packs in celebration of British Food Fortnight.

Special packs are on sale now to celebrate the event, which kicked off on 17 September and will run ­until 2 October.

Dairy Crest will further bolster the British cues of its Country Life brand with a re-run of its TV ad with The Sex Pistols’ John Lydon from 3 October.

“We believe that provenance plays a huge role in the quality of our butter,” said Country Life brand manager Sophie Lyons.
