As pressure for Pakistan's Prime Minister to step down mounted, Nawaz Sharif said Monday that he will neither resign nor go on leave despite rise of anti-government protests, Press Trust of India reported.

Addressing a meeting of leaders of political parties in Islamabad, the embattled Prime Minister said he would not allow a precedent under which a few people make hostage mandate of millions of people, referring to the weeks of protests led by opposition leaders Imran Khan, a hero cricket player turned politician, and firebrand Muslim cleric Tahir ul-Qadri.

"We have rule of Constitution here and we will not allow anyone to abrogate it," Express News quoted Nawaz as saying.

Following the meeting, a joint declaration stated that since the future of Pakistan is linked with democracy, any deviation from it could be dangerous for the federation of Pakistan.

So in a struggle to defend the democracy, leaders expressed their firm resolve of standing in support of the Prime Minister, with all parliamentary parties deciding to become party to the petition filed in the Supreme Court for supremacy of the Parliament, Radio Pakistan reported.

Specifically, attacks on the Parliament, Prime Minister's House and PTV were strongly condemned by the leaders. "These attacks are attacks on democracy and state," they said, condemning a section of the media for playing an irresponsible role in trying to create misunderstanding between institutions.

Meanwhile, leader of the Opposition in the Senate declared that if someone tried to besiege the Prime Minister House, then political leadership would stay with the Prime Minister in the PM House, according to PTI.

The meeting was attended by Syed Khursheed Shah, Mahmood Khan Achakzai, Maulana Fazlur Rehman, Ijazul Haq, Babar Khan Ghauri, Dr Farooq Sattar, Aftab Ahmad Khan Sherpao, Mir Hasil Bizenjo, Haji Adeel, Haji Ghulam Ahmad Bilour, Abbas Khan Afridi and Ghazi Gulab Jamal.

With 180 million people's history of coups and the government's struggle to tackle high unemployment, daily power cuts and a Taliban insurgency, the protests have raised questions over the stability of nuclear-armed Pakistan.

"Khan wants Sharif to step down because he believes the prime minister rigged last year's polls. Sharif won the election by a landslide, and the polls were the first democratic transfer of power in Pakistan's history," Reuters reported. "Qadri wants Sharif to step down because he says the system is corrupt. He has promised free housing for the homeless, and welfare and subsidized food and electricity for the poor."

Since the political crisis began, it has triggered violent clashes in Islamabad, leaving three persons dead and over 550 injured.
