Britain retained their men's Olympic track cycling team sprint title when they beat France again in world record time in this evening’s final giving Chris Hoy his fifth Games gold medal.

Philip Hindes, Jason Kenny and Hoy were ahead from the start and clocked 42.600 seconds to slash 0.147 off the record they had set in the first round.

The London Velodrome exploded with joy when Hoy crossed his finish line before Michael d'Almeida, with the Briton starting a lap of honour after taking his helmet off.

Germany took bronze by beating world champions Australia.

Hoy is now tied with rower Steve Redgrave as Britain's second most decorated Olympian behind cyclist Bradley Wiggins, who claimed his seventh Games medal by winning the time trial on Wednesday.

Germany ended up with gold in the women's team sprint after original winners China were relegated to second for a takeover infringement having earlier broken two world records.

Hosts and medal hopefuls Britain had been disqualified in the first round for another illegal changeover.

Gong Jinjie and Guo Shuang sped round the London Olympic velodrome like lightning in the qualifying and first round, notching world best times of 32.447 and 32.422 seconds.

They were slower in the final but it was still good enough to beat Germany until officials stepped in some minutes after the end of the race to say Guo had made a mistake on the changeover.

China were therefore bumped down to silver amid angry remonstrations between their team and International Cycling Union officials.

Australia took bronze by beating Ukraine and by the time of the medals ceremony, the Chinese duo had calmed down and accepted the warm applause of the slightly bemused crowd before Germany's golds were handed out.

Britain were not afforded the luxury of being dropped a position as Victoria Pendleton and Jessica Varnish were disqualified altogether in the first round for Pendleton's error in taking the lead over too soon.
