Each year, the Today programme hands over the editorial reins to five public figures, giving them a chance to decide what goes on the programme between Christmas and New Year.
Previous guest editors include Yoko Ono, Zadie Smith, Jarvis Cocker, Anthony Minghella, Professor Stephen Hawking, PD James and David Hockney.
This years editors, listed below, are responsible for between a third and a half of their programme's output, aided of course by Today's producers and reporters.
DIANA ATHILL - 27 DECEMBER
Diana Athill has enjoyed a gilded career, first at the BBC, then as literary editor and latterly as an award-winning memoirist. Now in her 90s, she recently moved into an old people's home and her impressions of this major change in her life have been a regular feature on the Today programme.
A staunch atheist, Diana Athill asks Archibishop of Canterbury Rowan Williams what faith, or the lack of it, tells us about a person. She also champions bedtime stories for adults.
COLIN FIRTH - 28 DECEMBER
Colin Firth, Bafta winner and Academy Award nominated actor, has starred in films including A Single Man, Mamma Mia and Love Actually. His latest film is The King's Speech.
Colin's programme investigates the effectiveness of international aid and whether the structure of our brains dictate our political inclinations. Also in his programme, Rupert Everett on homophobia in Hollywood and John Humphrys and Dame Edna Everage reunited.
SAM TAYLOR-WOOD - 29 DECEMBER
Sam Taylor-Wood was an influential photographer and conceptual artist before moving into the world of film-making. Her debut feature film as a director, Nowhere Boy, examined John Lennon's teenage years in Liverpool.

Richard will chew the fat with Peter O'Toole and reopens the case of James Hanratty, hanged for murder in 1961. And from de Manio to Peston, what makes a good broadcast voice?
