Presenting the new Sainsbury’s Christmas Advert. Mog sets off a chain of unfortunate events which almost ruin Christmas for the Thomas family. Can she pull it all back to save the day?This year, we worked in partnership with HarperCollins Children's Books and world renowned author and illustrator Judith Kerr to create a Christmas story based on her much loved character Mog.
