Easiest Knighthood decision all year. Well done Sir Ben Ainslie CBE.
Hampshire's Ben Ainslie is the greatest Olympic sailor of all time after winning his 4th gold medal in the Finn class. After the event he said that he was unlikely to compete in the next Olympics in Brazil but that winning was "an amazing feeling".
Ben Ainslie retained his gold medal title in the Finn class after holding off Denmark's Jonas Hogh-Christensen.
Hampshire's Ben Ainslie is racing off the coast of Weymouth in defence of his Olympic gold medal. Currently he is ahead of Denmark's Jonas Hogh-Christensen who started this race 2 points ahead of the British champion.
Race control has confirmed that GB sailors' Iain Percy and Andrew Simpson came 8th in the final race of the Star class in Weymouth. Since the Swedish team of Fredrik Loof and Max Salminen crossed the line first this means that GB has to settle for silver.
Sweden have won the Star class, but after a very tight race it looks like Britain are 7th which would give them a silver medal. Race control are still confirming the results.
Hampshire's Iain Percy and Dorset's Andrew Simpson are currently sitting 5th in their Star class race. The duo are defending their Olympic title from Beijing. If they win it will be the third gold in four Olympics for Iain Percy.
