He has faced Daleks, Cybermen and the Weeping Angels, but tonight the Doctor will face an even more terrifying foe: The One Show. 

New Doctor Peter Capaldi is set to appear on BBC1's topical magazine show at 7pm ahead of his debut on Saturday in series eight opener Deep Breath. 

The 12th Doctor will be interviewed by hosts Alex Jones and Matt Baker on his role, the upcoming series and – as is the show's trademark – other topics of the day. His appearance marks the final stretch of what has been a huge, worldwide tour to publicise the new series of Doctor Who. 

The synopsis for Deep Breath, airing at 7:50pm on BBC1 on 23rd August, is below.

"When the Doctor arrives in Victorian London, he finds a dinosaur rampant in the Thames and a spate of deadly spontaneous combustions. Who is the new Doctor and will Clara’s friendship survive as they embark on a terrifying mission into the heart of an alien conspiracy? The Doctor has changed. It’s time you knew him."
