You may want to tune in to BBC Radio 4 between 26 December and 30 December. They've got a slew of familiar names guest-editing the station for those four days, including the internet pioneer Sir Tim Berners-Lee, Barclays Chief Executive Antony Jenkins, Michael Palin, MI5 Director General Eliza Manningham Butler, and they've just announced two time Mercury Prize winner PJ Harvey will be added to that list.

Essentially what they'll be doing is setting the station's agenda, and with a lineup like that there's no doubt it should be pretty neat.
