Pakistan Awami Tehreek (PAT) chief Dr Tahirul Qadri has said that his party is not in favour of lock down but of knock down. Talking to media at London's Heathrow Airport on Thursday, he said that Imran Khan talked to me and apologised. "To lock down Islamabad is Imran and his party's decision. We do not support every point of Imran however; we are in favour to knock out the corrupt," he said. The leaders are creators of corruption; they don't have a right to remain in power, he added.
