ISLAMABAD - On the requisition of opposition parties, the National Assembly and Senate will meet tonight (Thursday evening) and heated debate on the recent spate of target killings in port city of Karachi and other issues is likely. The sessions requisitioned by the PML-N and MQM will continue for two days. The situation at the time of submitting the requisition is quite different as the MQM has once again mended fences with government, though partly. However, insiders in the MQM said that the party would definitely lodge strong protest on the floor of both the houses about the restoration of the Commissionerate System.
