Doctor Who stars Matt Smith and Jenna Coleman are to feature in two special editions of Blue Peter dedicated to the BBC sci-fi show, which celebrates its 50th anniversary later this month.

Coleman, who plays the Doctor’s current companion Clara Oswald, will answer viewers’ questions in a pre-recorded segment for the Doctor Who: Blue Peter Special on the CBBC channel at 5:30pm on Thursday 21 November, with 11th Doctor Matt Smith following her in the Doctor Who: Blue Peter Party at 9:30am on Saturday 23 November – 50 years to the day after the first ever episode of Doctor Who was broadcast.

The first Blue Peter special will also see the launch of a competition giving young fans the chance to design a sonic device for one of three Doctor Who characters – Madame Vastra, Jenny and Strax – while the Saturday edition will see a live audience joined in the studio by aliens from the series and challenged to design their very own monster.
