Pakistan Tehreek-i-Insaf (PTI) Chairman Imran Khan on Thursday announced that Islamabad protest will be held at any cost on Nov 2.

Talking to reporters in Islamabad, the PTI chief said protest is their "legal and constitutional" right.

"No power or deception can stop us from holding a sit-in in Islamabad," he said.

"People have decided to hold the corrupt prime minister accountable in Islamabad or he will have to resign," he said, adding that "the government is using illegal and unconstitutional tactics to refrain us from holding a peaceful protest."

The government's measures have been pushing the situation towards chaos, he said.

"I want to ask judicial institutions to halt the government from taking anti-democratic and revengeful measures," he said adding that their people were being arrested, raids were being carried out at printers and they (the government) were threatening transporters.

"My fervour, passion and enthusiasm have been increasing day by day and my conscience tells me the darkness prevailing over Pakistan will be eliminated shortly."

The PTI chief held a press conference, following a meeting of party's cadres to review the latest situation after the Islamabad High Court questioned Imran Khan's authority in announcing plans of a lockdown in Islamabad.

The court asked Islamabad authorities to ensure that no roads are blocked and all institutions function normally on Nov 2.

"We are not taking unconstitutional steps but the prime minister, whose corruption has been seen, is breaking the law. Holding a public office when you are suspected of committing a crime is unconstitutional," he said.

"We have been waiting for seven months that some institution would come forward and hold Nawaz Sharif accountable."

Imran's message to the police

Khan asked the Islamabad police not to act blindly upon directions being issued by the government against PTI.

“You are mistaken that you will go free after torturing peaceful protesters. The nation will not spare you and you will not be able to find a place to hide. Their (the government's) time is up. Who will provide shelter to you?”

He said, “It is my message for you: go by the book.”
