London 2012: 30,000 seats sold to British fans for 100m final

Fans from the host nation hold just 30,000 of the 80,000 tickets to the most highly-anticipated event of Games.

The remaining seats will be taken up by international supporters or reserved for the Olympic family, including officials, sports federations and sponsors.

London 2012 spokesman Jackie Brock-Doyle said: "We have 60,000 saleable seats in the stadium, 50% of them are going to the British public."

Sunday night's climax will see the fastest athletes on the planet go head-to-head.

But organisers said they could not give a more detailed breakdown of how seats for the dramatic showdown have been allocated until after the event.

Away from the stadium, in Stratford, east London, vast numbers of viewers are expected to tune in from across the world to see Jamaican sprinter Usain Bolt, 25, pitted against rivals in what promises to be one of the most talked-about races of the Games.
