Russell T davies has stepped down as Executive Producer of Doctor Who. He has been at the helm of the show since it relaunched in 2005.

BAFTA and Hugo Award-winning writer Steven Moffat will succeed Russell T Davies as Lead Writer and Executive Producer of the fifth series of the show, which will broadcast on BBC One in 2010.

Moffat has penned some of the series’ most unforgettable and acclaimed episodes, including Blink, with its terrifying weeping angels, for which he was awarded the BAFTA Writer Award 2008 on Sunday 11 May.

His previous work on Doctor Who includes The Girl In The Fireplace for series two, which earned him his second Hugo Award.

His first was for the series one two-parter The Empty Child, which became famous for its terrifying refrain “Are you my mummy?”

For the current series, Moffat has written Silence In The Library, a two-parter starring Alex Kingston which transmits on 31 May and 7 June 2008 on BBC One.
