ISLAMABAD- Minister for Information Pervaiz Rashid has rejected Pakistan Tehreek-e-Insaf chief Imran Khan's criticism of the PML-N government as unfounded. In a statement, he said PTI is scared of Prime Minister Nawaz Sharif, because it knows that if he could make Pakistan a nuclear state, he could also turn the country into a strong economy bringing prosperity to the people. The Minister said PTI has failed to deliver in Khyber Pakhtunkhwa in its one-year rule in the province so far. He said PTI wants to spread chaos and despondency in the country.
