The Jamaican's record-breaking run is the BBC's biggest day since the opening ceremony

An audience of 20 million people watched Usain Bolt win gold in the men’s 100 metres final last night, according to BBC figures.

As many as 19.4 million people tuned in to BBC1 to see the race – a 64.5 per cent share of the audience – with another 600,000 watching via the red button service.

The only part of the games to have attracted more viewers so far was last Friday’s opening ceremony, which had a peak audience of 26.9 million. Roger Mosey, the BBC’s director for London 2012, tweeted:
