Pakistan Prime Minister Imran Khan, in an interview with ARY News, said he will personally ask Boris Johnson for Nawaz Sharif’s deportation if the need arises. 

Pakistan’s prime minister said, his government is in regular contact with the British government for former Pakistan’s prime minister Nawaz Sharif’s deportation. Khan said his government is pushing for deportation as the extradition process would take much time.

Just days after, Nawaz Sharif addressed the first joint opposition rally, the Pakistan government had asked the British high commissioner to cancel his visit visa so that he could be deported back to Pakistan.
