It's been three weeks since Imran Khan and Tahir-ul-Qadri first called upon their supporters to march on Islamabad's high-security Red Zone, home to parliament and the offices of the Prime Minister. An estimated 50,000 people have continued to rally there, calling for Prime Minister Nawaz Sharif to stand down in what is now regarded as the longest-running protest in Pakistan's history.
