Glasgow-born actor and Oscar winner Peter Capaldi has been unveiled as the 12th incarnation of Doctor Who.

In a special one-off live television event on BBC One the next Doctor was revealed.

Capaldi was the bookies favourite to take the helm of the Tardis. He is best-known for his role as spin-doctor Malcolm Tucker in The Thick of It.

The 55-year-old replaces outgoing star Matt Smith.

Capaldi said of the role: "Being asked to play The Doctor is an amazing privilege. Like the Doctor himself I find myself in a state of utter terror and delight. I can't wait to get started."

Ahead of tonight's announcement, the identity of the doctor was apparently known to just 10 people, with bosses using the codename Houdini to try to keep it a secret.

The actor is a lifelong fan of the show and wrote a letter to the Radio Times about the Daleks when he was a teenager.

Capaldi won an Academy Award in 1994 for the best short film (Live Action) for Franz Kafka's It's a Wonderful Life.

He has also written several shows including a documentary about 500 years history of Scottish portrait painting and Cricklewood Greats - a spoof about the heyday of the British film industry.

He has appeared in Doctor Who before - playing Caecilius in the episode The Fires of Pompeii in 2008.

He will film his first scenes for Doctor Who this Autumn, but will appear in forthcoming films The Fifth Estate and Disney's Maleficent.

He is also currently filming new BBC One drama series The Musketeers, in which he plays Cardinal Richelieu which will launch in early 2014.
