Badminton stars in hot water

The Badminton World Federation is set to take action against four women's doubles pairs for deliberately under-performing at the Games.

A Chinese pair, plus two from South Korea and another from Indonesia seemed intent on trying to lose their matches on Tuesday night in an attempt to manipulate the draw.
The crowd became aware of what was happening and began booing the players, who hit shots long and wide on purpose and even served into the net, with many rallies no longer than four shots.
All four pairs had already qualified for the last eight and they were attempting to manufacture the positions they would finish in the group stage to determine their next opponents in the knock-out rounds.
Chinese top seeds Wang Xiaoli and Yu Yang set out to lose against Koreans Jung Kyung-eun and Kim Ha-na which meant they came second in the group and avoided a clash with compatriots and second seeds Tian Qing and Zhao Yunlei.
The Koreans responded to China's antics by copying them and referee Thorsten Berg stepped in to warn the players, with the Koreans going on to win 21-14 21-11.
Then a second Korean pair, the third seeds Ha Jung-eun and Kim Min-jung, attempted to lose their match against Indonesia's Meiliana Jauhari and Greysia Polii in an apparent retaliation to avoid Wang and Yu in the quarter-finals and the Indonesians responded to the Koreans by trying to lose themselves.
A statement from the BWF confirmed that all four pairs would face charges of "not using one's best efforts to win a match" and "conducting oneself in a manner that is clearly abusive or detrimental to the sport" with a disciplinary hearing set to be held on Wednesday morning with a decision on their future announced later.
