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

Two pairs of our sailors were in with a shout of gold in the 470 class at Weymouth.

But both Luke Patience and Stuart Bithell - and now Hannah Mills and Saskia Clark - have had to settle for silver.

Daniel Fogg's also just missed out on a medal in the men's 10 kilometre open water swimming.

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 later.

Better news for Lutalo Muhammad, who's through to the men's quarter-finals - while canoeists Ed McKeever and Jess Walker have each qualified for tomorrow's 200 metre kayak single finals - along with the men's doubles team.
