While strongly opposing army in Karachi, he said that the army would not be able to stay or to walk if it was sent in the narrow streets of the metropolis.
The PML-N leader said that political parties in Karachi were playing in the name of maintaining law and order in the city.
Nisar alleged that every militant group in the metropolis is patronized by the political parties of the ruling coalition.
Earlier, Nisar, who chairs the Public Accounts Committee (PAC) dissolved all the PAC’s special committees and sub-committees.
He said that the PAC could not be made to accommodate the government’s necessities and agenda.
A statement issued by Mr Khan said that no special or sub committees of the PAC could hold any meetings before a proper meeting of the PAC itself.
Moreover, Mr Khan said that the government had given the position of auditor general of Pakistan to a controversial figure which laid bare the government’s intentions.
Earlier on Tuesday, the government appointed Akhter Buland Rana as the auditor general of Pakistan for a four-year term.
The Pakistan Muslim League – Nawaz (PML-N) has opposed the appointment because it considers Mr Rana a controversial figure, saying that charges of irregularities are pending against him.
