Final figures for Episode Eight, The Hungry Earth, published by BARB show the story was watched by 6.49 million viewers.
The figure is an increase of over two million on the initially reported overnights, implying many recorded the programme to watch it later. Although the overnight figure was the lowest reported since the series returned, the final figure beats three David Tennant episodes.
On BBC One the programme got 6.01 million watching where it was the ninth most watched programme for the channel for the week. An additional 0.48 million watched on BBC HD. When added together the programme totalled 6.49 million viewers and was the 19th most watched programme of the week.
The BBC Three Sunday repeat did not rank high enough to get into the top 30 for the week.
