Gavin & Stacey creators James Corden and Ruth Jones will appear at Hay Festival this summer

The duo will take to the stage on 23 May to talk about their new behind-the-scenes book as well as the show's origins and final episode.

More than 19.1 million viewers watched the series come to an end on Christmas Day, making it one of the most-watched scripted TV shows of the century.

Musician Billy Ocean, broadcaster Stacey Dooley, children's author Jacqueline Wilson and Strictly Come Dancing judge Anton Du Beke are also set to appear at the annual literary festival in Powys.
