Ahead of Gavin and Stacey’s final episode, Ruth Jones says she and co-writer James Corden feel like their characters really exist.

“James and I always felt – I know it sounds a bit strange – that they really existed. So it’s not like they’re dying,” Jones told Radio 2’s Zoe Ball.

“For us, they continue to live their lives in Barry or Billericay. It’s just that we are no longer a part of what’s happening in their lives.”

The final episode will air on BBC One on Christmas Day.
