Supermarket chain Iceland is giving away 'black cards' which will entitle shoppers to a year's supply of frozen chicken for free.

Five cards have been hidden in stores across the country, and can be used on a range of 215 different frozen chicken products.

The supermarket, which has a branch on Clapham High Street, says it wants to celebrate mothers with its V.I.C (Very Important Chicks) card.

Shoppers who find a VIC card will need to notify a staff member to verify the win.

And there is also a chance to win online, with shoppers able to nominate someone on Iceland's Instagram page. The social media winner will be randomly selected on May 23.

Samuel Robbins-Wells, head of category at Iceland, said: "Unlike other brands, our V.I.C card is created with mums in mind. 

"We wanted to give back to the V.I.Cs who come to our stores for their weekly shop. 

"As the home of many amazing partnerships and exclusives, all shoppers who visit us instore and online can make the most of the value we offer and pick from our varied range of frozen products to find something the whole family can enjoy."

The black cards were hidden yesterday (May 15).
