The International Cricket Council (ICC) has announced a “zero tolerance” crackdown on offensive language and gestures in the sport. As part of its drive to eradicate “sledging,” the ICC sent a letter to international match officials and the captains and chief executives of full-member teams and top one-day sides calling for their support. The letter, published by the Hindustan Times on Monday, has asked all concerned to learn from India's tour of Australia . “It was announced that the ICC would in future be taking a zero tolerance approach to the use of offensive language,” the letter stated. “We acknowledge that every incident is highlighted and sensationalised in the media, often with very little objectivity, but ... there have been several controversial incidents on the field which originated from the use by players of language or gestures which are considered obscene, offensive or insulting.” The umpires have to decide what they felt were acceptable levels. __
