David Florence won silver for Britain after a perfect run in the slalom canoeing final at the Shunyi white water park.

The 26-year-old is Britain's first slalom canoeing medallist since Gareth Marriott also won silver at Barcelona in 1992.

Florence came into the final in fourth place and produced a faultless run which propelled him above Poland's Krzystof Bieryt and Czech paddler Stanislav Jezek.

He was in first place until Slovakian world number one Michal Martikan claimed gold with the last run of the final.

Earlier on a dramatic day for Britain, 2004 Olympic silver medallist Campbell Walsh crashed out of the kayaking competition when he finished last in the semi-final.
