Resurgent Greene wins thriller

World 400m hurdles champion Dai Greene wins the British Championships in a season's best time of 48.66 seconds, holding off fellow Welshman Rhys Williams in a dramatic finish.

The performance marked a return to form for Greene who had not won previously this season and was beaten by Williams on the same track in the Birmingham Diamond League two weeks ago.

Williams could not outpace Greene in the home straight, despite running a personal best of 48.85 seconds.
