manchestereveningnews.co.uk:

Gavin And Stacey star James Corden has said his character - Neil 'Smithy' Smith - and Vanessa 'Nessa' Jenkins had to 'end together' in the show's final episode on Christmas Day.

The 46-year-old was speaking in the Gavin And Stacey: A Fond Farewell documentary which aired on Wednesday night (January 1), a week after the the finale of the beloved sitcom aired.

More than 12 million viewers tuned in. During the one-off episode to mark Gavin and Stacey: The Finale, James also revealed Sonia, played by Laura Aikman, who Smithy is seen preparing to marry at the start of the Christmas Day episode, was brought back as she 'wasn't in people's minds'.

The finale saw Smithy finally decide to marry Nessa, played by series co-writer Ruth Jones, after aborting his wedding to Sonia at the altar, while Stacey’s mother Gwen West (Melanie Walters) is revealed to be in a secret relationship with Dave Coaches (Steffan Rhodri).
