Tesco has enlisted Roisin Conaty and Anna Maxwell Martin for its 2026 Christmas campaign, which sees Conaty play Polly, a Tesco delivery driver, and Maxwell Martin star as Lizzie, her former school friend.

When Lizzie accidentally sends her Christmas grocery order to her old address, Polly steps in to save the day. A spokesperson for the supermarket commented 'This Christmas, Tesco is going to be showing up with the extra little help that our customers need to deliver their very best Christmas, whether that's cracking deals on the products they love, delicious food and drink, or festive experiences that help bring families together'.
