British windsurfer Nick Dempsey on course for Olympic silver medal

Great Britain's Nick Dempsey has all but secured a second successive Olympic silver medal with a race to spare.

A day shy of his 36th birthday, the windsurfer ensured he will add to his Beijing 2008 bronze and second-place finish at London 2012.

Dempsey began his final Olympic regatta on top but was eventually pipped to gold by Holland's Dorian van Rijsselberghe - the same as four years ago.

The result is subject to protest and both will still have to sail in Sunday's medal race, but the pair were congratulating one another at the end of race 12.
