MQM leader Haider Abbas Rizvi has said that workers of Pakistan Tehreek-e-Insaaf are frustrated with their leaders who left them at the venue of the march and went to their homes. In a TV interview on Saturday, he said as compared to PTI, there are more people in the march of PAT chief Dr Tahirul Qadri. He expressed his sympathy with the PTI political workers as they were facing the vagaries of the weather. He said MQM workers staged a five-day sit-in at Numaish in Karachi as the leadership stayed among them.
