Seb Coe: 'Olympic badminton controversy is depressing'

The London 2012 chairman Lord Coe has described the behaviour by several female Olympics doubles badminton players as "depressing" and "unacceptable".

The Badminton World Federation has disqualified eight players from the Olympics after accusing them of "not using one's best efforts to win".

Four pairs of players - two from South Korea and one each from China and Indonesia - are out of the Olympics after their matches on Tuesday.

All four pairs were accused of wanting to lose in an attempt to manipulate the draw for the knockout stage.
