The first trailer for the “Gavin and Stacey” Christmas special has been unveiled.

The new teaser sees Uncle Bryn (Rob Brydon) trying — and failing — to cook everyone a nice Christmas dinner, while Stacey (Joanna Page) and Nessa (Ruth Jones) look on in shock as he ends up dropping everything.

Brydon’s character then has no choice but to delay the festive feast.

Fans discovered the secret teaser clip in season 3’s finale as they binge-watched the show on BBC iPlayer.

Corden and Ruth Jones said they’d been secretly plotting its return for years after the last episode was broadcast in 2010.
