ByTariq Butt ISLAMABAD: Tensions between the opposition and Speaker Asad Qaisar are bound to exacerbate after he said that certain matters, including payments made by the National Accountability Bureau (NAB) to Broadsheet and another related overseas firm, were beyond the purview of the Public Accounts Committee (PAC). The speaker has told PAC Chairman Rana Tanveer Hussain, who belongs to the opposition Pakistan Muslim League-Nawaz (PML-N), that the accountability committee cannot under the rules take up for review payments made by NAB to Broadsheet as well as the affairs pertaining to an agreement worked out by the postal department. However, the PAC chief, quoting the rules, told the speaker bluntly that the forum was fully authorised to examine the objections noted by the auditor-general of Pakistan (AGP) on all the dealings concerning foreign assets recovery firms and the postal department so that losses to the national exchequer were highlighted and those responsible punished.
