I PROMISE to win an Olympic medal for the Thai people. From the very beginning of the rumours that said I failed a dope test, I was downhearted but still never quite lost hope," badminton sensation Ratchanok "May" Intanon said while shedding tears during yesterday's press conference, which cleared the star athlete of a doping violation.The ad-hoc meeting, chaired by Badminton Association of Thailand (BAT)'s president Khunying Patama Leeswadtrakul, was held at Anoma Grand Bangkok Hotel in front of a large number of sport journalists to announce the Badminton World Federation (BWF) Anti-Doping Panel's decision on Ratchanok's case.
