Sir Chris Hoy has won a fifth Olympic gold after Great Britain's men's team sprint squad triumphed on a night of high drama at the London 2012 Olympic Velodrome.
After Victoria Pendleton and Jess Varnish were relegated from the team sprint for a takeover infringement and Britain's men's team pursuit quartet set a world record, Hoy, Philip Hindes and Jason Kenny progressed to the final of the three-man, three-lap team sprint in a world record of 42.747 seconds.
The British trio clocked another world record in a stunning finale, finishing in 42.600secs.
In a repeat of the final four years ago in Beijing, France's Gregory Bauge, Michael D'Almeida and Kevin Sireau had to settle for silver, finishing in 43.013.
