The former International Cricket Council boss, Malcolm Speed, says there's a compelling case to suspend Pakistan from world cricket.
Speed, who was chief executive of the ICC from 2001 until 2008, said suspension is a serious option for Pakistan.
Pakistan's heavy test loss to England at Lord's featured three dubious no-balls, allegedly the subject of a match-fixing agreement, carried out by British tabloid News of the World in a sting operation.
The newspaper says it paid $325 thousand to a middle man in return for details about the timing of the no-balls.
Pakistan captain Salman Butt and bowlers bowlers Mohammad Aamer and Mohammad Asif have been questioned by police in England.
Speed says match fixing appears endemic and Pakistan may need a break from international competition.
