The first gold medal of the London 2012 Olympic Games has gone to China.

Shooter Yi Siling won the women's 10-metre air rifle title at the Royal Artillery Barracks in Woolwich.

The 23-year-old world number one lived up to her billing as favourite by beating Poland's Sylwia Bogacka into second. Bogacka qualified in first place and was leading until the eighth shot, when a wayward effort condemned her to silver.

China's Yu Dan collected the bronze medal with Beijing gold medallist Katrina Emmons fourth.

Yi, speaking after receiving her medal from International Olympic Committee chairman Jacques Rogge, said: "I'm very happy. I want to say thanks to China, to my mother and father.

"I'm very excited and happy. I have been shooting since I was 13-years-old.

"I've been up since 5am this morning. There was a lot of pressure on me."
