It's been a mixed day so far at the Olympics for Team GB. 

Sailors Luke Patience and Stuart Bithell couldn't beat the Australians in the 470 class down at Weymouth - so take silver.

Sarah Stevenson's hopes of adding another Taekwondo gold for Britain are over after a shock defeat in her opening match - but she could still fight for a bronze medal later.

Better news for Lutalo Muhammad, who's through to the men's quarter-finals.

Elsewhere, Canoeist Ed McKeever's qualified for tomorrow's final in the 200 metres kayak.

And Daniel Fogg is in the men's 10 kilometre open water swimming now.
