Olympic champion Abhinav Bindra today backed the Sports Ministry's decision to suspend the Indian Olympic Association. He called it a "good step" following the sports body's move to honour two scam-tainted administrators.The 2008 Beijing Olympics gold medallist said that change in Indian sport will only happen if mandated. A law is necessary in India, he added. The IOA named its former presidents Suresh Kalmadi and Abhay Singh Chautala as life presidents on Tuesday. The decision has been heavily criticised as both are facing allegations of corruption. As a result, the Vijay Goel-led ministry yesterday suspended the IOA. The Sports Ministry suspended the Olympic body till the time it reverses the decision to make the tainted duo of Kalmadi and Chautala its life presidents. The government took the firm decision after IOA failed to reply to its showcause notice within the deadline.
