Most cases against Altaf withdrawn, says Sindh CM
LAHORE: Most of the cases against Muttahida Qaumi Movement (MQM) chief Altaf Hussain have been withdrawn, a private TV channel quoted Sindh Chief Minister Syed Qaim Ali Shah as saying on Tuesday. According to the channel, Shah told a press conference in Hyderabad that the step had been taken in pursuance of the government’s reconciliation policy. He said the cases had been withdrawn but it had been left to the discretion of the MQM chief whether to return to Pakistan, adding he was free to come. Shah said the majority of the cases against Hussain had already been withdrawn and the government would review other cases registered against him. daily times monitor
