Mr Gammon designs costumes for SAINSBURY'S CHRISTMAS

As well as 8 year old lead Tia Isaac's star costume, Mr Gammon's work includes the entire cast of almost 60 children from across the UK playing a host of Christmas characters, such as a nativity camel, baubles and presents, a drummer dressed as a turkey, the Queen in a TV box giving her Christmas speech, and even a set of fairy lights – including the plug.

The heartwarming ad is directed by THE GREATEST SHOWMAN director Michael Gracey, marking the launch of Sainsbury's “We give all we’ve got for the ones we love” Christmas campaign.
