ISLAMABAD - Chairman Pakistan Tehreek-e-Insaf (PTI) Imran Khan will address a public gathering in Attock on June 14 where a large number of locals are likely to formally join the party. Imran Khan has said that Pakistan is heading toward the change and conventional politics is giving way to a new brand of politics and politicians. The youth is acting as a catalyst of change. He expressed these views during conversation with a delegation from Attock led by Qazi Khalid Mehmood ex-Tehsil Nazim Attock, who called on him here at Party Central Secretariat on Tuesday. The delegation invited PTI leader to address a public gathering in Attock on June 14, which, Imran Kahn has accepted. In a statement, Imran Khan said that the PTI would mobilise the youth to restore the sovereignty of Pakistan. The public mobilisation would include surprise and unannounced blockade of NATO supply line in different parts of the country. If the govt used force against the peaceful demonstration for change, the PTI will seek legal redress from Supreme Court as this peaceful movement is for the implementation of joint resolution of Parliament, he added.
