Xiang Liu was crowned world champion over 110m hurdles in Osaka after he took the gold medal in a time of 12.95 seconds.

The Olympic champion was drawn widest of the finalists but produced a tremendous late surge to overhaul American Terrence Tramell in the final strides to take the title.

Tramell crossed the line in 12.99 with compatriot David Payne claiming a superb bronze in a personal best of 13.02.

The winner reflected afterwards: "Running lane nine was both good and bad. It forced me to run my own race and showed that I'm a person with self-control."
