Pakistani opposition leader Imran Khan has promised to continue his anti-government protests until Prime Minister Nawaz Sharif resigns over alleged vote fraud in last year’s elections.

On Sunday, Khan told his supporters in central Islamabad that he would not back down from his demand for Sharif to step down and urged more protesters to join him.

The cricketer-turned-politician urged the protesters to stand against the politicians in power in the country, warning that if they don’t, they will be “enslaved.”

“I assure you [that] Nawaz Sharif, who is like an emperor, a king… until he steps down, I will not move from here,” he added.

Khan, who heads the Tehreek-e-Insaf (PTI) party, and cleric Tahir-ul-Qadri, the head of Pakistan Awami Tehreek (PAT), have been leading daily protest rallies in Islamabad since August 14.

The two opposition figures say the country’s May 2013 general elections, which was won by Sharif’s Pakistan Muslim League-N (PML-N) party, was fraudulent. They want Sharif’s resignation and an overhaul of the country’s electoral system.
