Miranda Hart is taking over Channel 4 with a one-off Christmas party, celebrating all that is amazing (and not so amazing) about Christmas. Expect celebrity guests, festive surprises and a definitive answer on whether or not nuts belong in a Christmas Pudding.

She's carol singing with a very special guest singer, hitting the streets to spread Christmas joy among shoppers, rewarding the good deeds of unsuspecting members of the audience, and bringing romance to two singletons. And there's a gospel choir performing a unique Christmas mash up, plus a spectacular festive version of a Destiny's Child classic. Special guests include David Tennant, Sam Smith, Prue Leith and Susan Calman.
