Unofficial overnight figures show that episode one of Prisoner of the Judoon was watched by 0.6 million viewers. The audience share was 5.9%. An extra 40,000 people watched in high definition on the BBC HD channel.
The rating is similar to that which The Sarah Jane Adventures received in the same slot last year. It is around 50% higher than the average for the timeslot on BBC One. Last week's edition of SMart achieved 0.4 million.
Final figures will include those who record the programme and watch it within seven days, and will be released by BARB in two weeks time.
