The protesters have been holding demonstrations since they assembled in Islamabad in mid-August. When they tried on Saturday evening to march on the Prime Minister's house, police used tear gas and batons to repel the protesters, many of whom were armed with sticks and sling shots. Officials confirmed that three people had been killed and hundreds needed treatment.
Mr Sharif was elected to his third term as Prime Minister in May last year, with Mr Khan's Pakistan Tehreek-e-Insaf (PTI) party coming second in many major cities. Mr Khan accepted the results, but called for a probe into alleged vote rigging. He launched his so-called freedom protest after claiming the government and the election commission had failed to follow up on its agreement to launch an inquiry.
Yesterday, Mr Khan also faced claims from his own senior party members that he had allowed the protesters to go too far. Veteran Pakistani politician Javed Hashmi claimed the party had agreed protesters would not march on the PM's house but that had been overturned by Mr Khan.
"No distance has been left between martial law and us," said Mr Hashmi, who said he could not support protesters marching to the PM's home.
Mr Sharif has insisted he will not stand down and has accepted the protesters' demands for a court-appointed inquiry of a number of disputed constituencies.
