Pakistani cricketers Salman Butt and Mohammad Asif were found guilty of fixing parts of a Test against England in a case that has thrown the credibility of the international game into doubt. Former Test captain Butt, 27, and fast bowler Asif, 28, face jail after a court in London convicted them of deliberately bowling three no-balls during the Lord's Test in August 2010 as part of a "spot-fixing" betting scam. The cricketers who have defamed the country internationally must be given exemplary punishment so that no one dares defame the country again. I suggest no leniency should be observed to them and their guilt be treated as treason. MOHAMMAD KHAN SIAL, Karachi, November 2.
