Tom Daley delighted to seal World Series gold medal in London

Great Britain's Tom Daley has expressed his joy after winning a gold medal in the 10m platform at the FINA Diving World Series in London.

The 20-year-old pipped China's world-record holder Jian Yang and Olympic silver medallist Qui Bo to the top spot with a score of 554.05 on Sunday.

Daley also displayed his 'firework' routine, which he debuted in February at the British Gas Diving Championships, and received a score of 99.00.

"I knew I had this in the tank and that I could beat the Chinese," Daley told BBC Sport. "It is the highest I've ever scored with a 'twister' routine in my life, so it's great for it finally to work in competition."

Daley had not won a World Series title since April 2013.
