The BBC have confirmed that the long awaited series four of Doctor Who will start soon - on Saturday 5th April.

The series, which features Catherine Tate reprising her role as Donna Noble, and more guest appearances than you can shake a stick at, will be the last full series until 2010 - and is widely expected to be the last for both David Tennant and writer/producer Russell T Davies, although there will be a number of "specials" through 2009.
