Pakistan Interior Minister Rana Sanuallah has said that the government plans to consult experts on initiating a process to declare Imran Khan's Pakistan Tehreek-e-Insaf party a “proscribed” outfit after police claimed to have seized weapons and petrol bombs from the former premier's residence in Lahore. Leaders of the ruling alliance lashed out at Khan who travelled from Lahore to Islamabad on Saturday to mark his presence at a district court here, amidst mayhem and chaos, as his supporters clashed with police. While Khan was in Islamabad, over 10,000 armed Punjab police personnel launched a major operation at his Zaman Park residence in Lahore and arrested dozens of his supporters and claimed to have seized weapons and petrol bombs.
