South Korea's Park Tae-hwan got down on his knees and begged for the chance to compete at the Rio Games on Monday as the Korean Olympic Committee (KOC) shows no signs of lifting the additional doping sanctions it has imposed on the swimmer.

Park was banned for 18 months by governing body FINA after testing positive for testosterone ahead of the 2014 Asian Games, and while the ban expired in March he must now wait three more years before he can be considered for selection under KOC rules.
