Three TV shows had over 10 million viewers in Sunday night's ratings.
Over on BBC One, the prime time schedule started with the Strictly Come Dancing results.
The pre-recorded episode between 7:15PM and 8PM averaged 10.8 million viewers, up 100,000 on last weekend's results to give Strictly its highest Sunday night figure of the year.
The Strictly Come Dancing results from Blackpool saw viewing figures peak with over 12.1 million watching.
Strictly was the most watched show of the night, just taking the lead from Blue Planet 2 which had 10.75 million viewers. The fourth of seven episodes was down around 100,000 viewers on last weekend's number, as the Sir David Attenborough narrated doc looked at life of sperm whales.
Over on ITV, with an average audience of 4.8 million tuning between 7:30PM and 9PM on ITV last night, The X Factor was up 100,000 viewers week-on-week.
It was the second rise in as many weeks for the Sunday show, despite clashing against Strictly and Blue Planet. It was the most watched Sunday episode of the X Factor live shows so far this year as two acts got the boot.
At 9PM, the return of I'm A Celebrity had 10.4 million viewers from 9PM. This is down slightly from 2016 but up on both 2015 and 2014.
