Footie fans will be in with a chance to win one of 100,000 exclusive Euro 2012 England shirts through a new Mars offer.

The brand is marking its status as the England teams’ official snack supplier with a push under the tagline ‘Work, rest, play your part’.

Consumers can go online and enter a code found inside special packs, which are rolling out next month, to see if they have won a shirt.

The £4.3m promotion will be backed by digital activity and a TV ad push breaking on 15 April.
