"This is a revolution. Look at them people. They are fed up with the status quo. This is an across-the-board desire for change and a fear the country won't survive unless we do.
It's middle classes, young people, people who have never voted before, exactly like what happened in the Arab world. We are going to sweep this election," Imran told The Sunday Times.
An outspoken critic of US drone attacks inside Pakistan targeting Taliban and al Qaeda elements, Khan has argued that the CIA-operated unmanned aerial attacks kill thousands of civilians and stoke resentment that creates more supporters for the militants.

"We never had a problem with the tribal areas until General (Pervez) Musharraf sent troops in in 2004," Imran said. "They are like a bull in a China shop and have taken us into a never-ending war."
Echoing Imran's views, former prime minister and PML-N chief Nawaz Sharif told the Times that "drones are mostly killing innocent people. They are making the situation worse rather than better. If I am elected, I will tell the Americans that clearly this is counterproductive, threatening our sovereignty and must stop."
