SYDNEY (AFP) - Five-year bans handed to three Pakistani cricketers for spot-fixing offences were too lenient, according to a survey of international players released Thursday. Over three-quarters of respondents to the Federation of International Cricketers Associations (FICA) players survey, said the bans meted out to Salman Butt, M Asif and M Aamir were inadequate. The trio, accused by Britains News of the World of conspiring to deliberately bowl no-balls as part of a 'spot-fixing betting scam last year, were banned by the International Cricket Council (ICC). All deny wrongdoing and are appealing the verdicts at the Swiss-based Court of Arbitration for Sport (CAS). The vast number of players want significant penalties to be invoked against those who are found guilty of serious corruption offences, said FICA chief executive Tim May. Whilst 100pc of players say that they will report any corrupt approaches made to them, 20pc of them do not have confidence in the ICC to treat this information confidentially.
