Women's singles titleholder Gong Ruina was deposed at the world badminton championships on Sunday, beaten 11-6, 11-3 in the final by Chinese compatriot Zhang Ning.

Gong led 4-0 in the first game but once Zhang found her stride she was generally in control, rounding off a fine week during which her other scalps have included the 1999 world champion Camilla Martin of Denmark.

Seeded second ahead of Gong at four, Zhang, a comparative veteran at 28, was competing in her sixth world championships.

The men's singles final later on Sunday is between China's Xia Xuanze, the fifth seed, and ninth-seed Wong Choong Hann of Malaysia.
