Twins have appeared in their first TV advert for a supermarket chain.

Four-year-old Bobby and Duncan MacDonald, of John Ray Gardens, in Braintree, have starred in Tesco’s Christmas advert, which was aired for the first time last Sunday.

Their mum, Anna, was very surprised to hear the boys, who were born prematurely at 33 weeks, had got the part, and they began filming in Elstree on October 14.

She said: “I am really pleased with the advert."
