Crime writer Val McDermid and poet Roddy Lumsden team up for Scotland for the first time, as Tom Sutcliffe chairs the fourth contest in the 2014 series. Their opponents are Diana Collecott and Adele Geras of the North of England.
As always, to answer the trademark cryptic questions of Round Britain Quiz they'll have to marshal snippets of trivia concerning everything from Egyptian gods and hidden rivers of London, to children's fiction and the members of the current coalition cabinet.
Tom is on hand to ensure fair play and to guide the teams gently out of their more misguided blind alleys. The programme includes some more of the most interesting recent ideas sent in by listeners.
Producer: Paul Bajoria.
