The BBC gave viewers an unexpected eyeful during the live broadcast of its nightly news show when someone in the newsroom appeared to be watching a steamy film behind an oblivious presenter.

Sophie Raworth was anchoring the News at Ten when a screen behind her started playing a film in which a woman is topless.

The unexpected clip could be clearly seen by the show’s 3.8million viewers, and was being watched by a man wearing headphones in the room behind the news show.
