TEAM GB's Ben Ainslie became the most successful sailor in Olympic history after today securing a fourth successive gold medal.

The 35-year-old replaced Denmark's legendary Paul Elvstrom as the Games' most decorated sailor after triumphing on home waters in front of thousands of supporters in Weymouth.

Ainslie faced fierce resistance throughout the week from Elvstrom's countryman Jonas Hogh-Christensen, although he managed to finish ahead of the Dane in this afternoon's medal race to increase his Olympic haul to four golds and a silver.
