Doctor Who series nine begins tonight in the explosive Magician's Apprentice – and in honour of the great day, we're giving you an exclusive photo gallery with series stars Peter Capaldi and Jenna Coleman, taken recently in Cardiff.

The pictures see both actors in character as the Doctor and Clara, with Peter Capaldi modelling his stylish new Jon Pertwee-style outfit (that will debut in this series) and a pair of sunglasses that play a role in today's episode.

You can see some of these photos and the interview that accompanies them in this week's Radio Times, where the actors also reveal a few secrets of their partnership and why their time in the Tardis has been such a success.

Doctor Who series 9 begins on BBC1 tonight (Saturday 19th September) at 7.40pm
