Greene claims Britain's first gold
Dai Greene has ended Britain's wait for a World Championship gold medal with victory in the 400 metres hurdles in Daegu.
The 25-year-old went one better than silver medal winners Jessica Ennis and Mo Farah to claim victory in 48.26 seconds.
The Welsh athlete passed Puerto Rico's Javier Culson in the final 20 metres before spreading his arms in celebration as he crossed the line.
Greene held his nerve after all the athletes were called back to their blocks after a faulty start and were then told to stand up again before the race got under way.
Culson went out hard over the first 200m but Greene always looked comfortable and, coming round the final bend in third, picked off South Africa's LJ van Zyl before reeling in the Puerto Rican.
Greene, who had looked a picture of concentration and confidence before the race, has now won the World, European and Commonwealth titles.
Culson took the silver in 48.44secs with van Zyl getting bronze in 48.80.
