Islamabad: Pakistan's hard-line cleric Maulana Fazlur Rehman gave Prime Minister Imran Khan a two-day ultimatum to resign, saying that he must step down without testing the patience of peaceful protestors.

Addressing a massive protest rally, dubbed 'Azadi March', held in Pakistan to topple the incumbent government, Rehman said that only people of Pakistan and not any "institution" had the right to govern the country.

Rehman also called a multi-party conference at his residence here to decide the future strategy against the government. Pakistan People's Party chairman Bilawal Bhutto-Zardari; Pakhtunkhwa Milli Awami Party chairman Mehmood Khan Achakzai; Pakistan Muslim League - Nawaz (PML-N) leaders Ahsan Iqbal and Khawaja Asif and Awami National Party (ANP) general secretary Mian Iftikhar Hussain attended the meeting.

Along with Rehman, leaders of the PML-N, PPP and ANP participated in the march held to topple Pakistan Tehreek-e-Insaf government led by Prime Minister Imran Khan.

"The elections of July 25 were fraud elections. We neither accept the results nor the government that came into power after those electionsWe gave this government one year but now we cannot give them any more time," Rehman said.

In retaliation, the Pakistan Army on Saturday warned that no one will be allowed to create instability and chaos in the country. 

"Maulana Fazlur Rehman is a senior politician. He should clarify which institution he is talking about. Pakistan's armed forces are an impartial state institution which always supports democratically elected governments," Pakistan Army spokesman Major General Asif Ghafoor said in response to Rehman's remarks.

"Nobody would be allowed to create instability as the country cannot afford chaos," he warned.

Ghafoor said the army was neutral and supported democratically elected governments in accordance with the Constitution.
