The Angels Take Manhattan had an overnight audience of 5.9 million viewers, a share of 26.9% of the total TV audience.
The audience increased throughout the episode, as more viewers joined to witness the departure of 'The Ponds', peaking at 6.4 million for the last five minutes.
Doctor Who was the highest rated programme on BBC One for the day, with the other drama of the evening, Casualty, getting 3.7 million viewers.
Highest programme of the day was The X Factor which had 8.7 million watching. Against Doctor Who, ITV 1's Red or Black? had 3.5 million viewers.
With Sunday's ratings still to come, Doctor Who is at 19th place for the week. Final consolidated figures, which will be available next week, should see this position rise.
