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 grabbed the same colour 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.
