Blue Planet returned to the BBC last night with staggering ratings which saw it beat talent competitions The X Factor and Strictly Come Dancing as well as last year's premiere of the acclaimed Planet Earth II.

The David Attenborough-narrated documentary series was seen by an average of 10.3 million live viewers stealing the channel's crown from Strictly, the results show of which was watched by an average of 9.6 million viewers just before.

A peak of 10.6 million viewers caught the episode which stunned audiences with its underwater scenes involving bottle-nosed dolphins, killer whale and a clam-loving tusk fish equating to more than a 41 percent of the UK audience share.

In comparison, last year Planet Earth II launched with overnight figures of 9.29 million viewers.

This year's first live X Factor results show attracted 4.3 million viewers on ITV. Judge Simon Cowell was absent from the weekend's shows after suffering a fall in his home on Friday.
