Opposition Leader in the National Assembly Chaudhry Nisar Ali Khan has said that he challenge Imran Khan that he never paid a penny as tax since 1971 to 1991. Speaking to media on Thursday, the PML-N stalwart said that they were fed up of daily blame game and wanted to take the it to a logical end.  He said that Imran Khan said he would move courts against the PML-N leaderships. ” Now i accused you of tax evading, now bring me to any  court,” Chaudhry Nisar said. He Khan was a tax evader and mater of U-turn who could not see corruption of Asif Zardari. “The politics of Imran Khan is nothing else but mere accusations and allegations; always Mian Nawaz Sharif and PML-N used be the main targets of his,” said Leader of the Opposition. Responding to Imran Khan’s allegation that Nawaz Sharif’s son, Hasan Nawaz, has accumulated Rs50 billion abroad, Nisar said Hasan has a legal and lawful property in England, saying that “Khan is free to sue him in Britain if he is much concerned.” Nisar launched tirades against Khan a day after another PML-N leader, Khawaja Asif, blamed Khan for gambling $1.8 million zakat money in real estate abroad. Khan denied the charge. “We have been raising voice for this country at every forum; inside and outside the Parliament. Be it Kerry-Lugar Bill or NRO or any other black law, we have resisted before the rulers’ designs,” Nisar added while countering Khan’s remarks that “PML-N is destabilizing the country through its policies.” The PML-N leader said Rehman Malik and Imran Khan both target Nawaz Sharif with baseless charges. “They should go to court of law if they possess evidences against our party chief and his son.” "A judicial commission should be formed to investigate claims from both the sides, or Chief Justice of any High Court can also probe into such charges," the opposition added further. “Khan is mater of U-turns. He has a track record of changing statements and stands,” Nisar said. Nisar said that Imran never criticized the government, MQM, ANP and Q- League.
