Islamabad: Attacking the powerful military establishment of the country for putting "pressure" on Prime Minister Zafarullah Khan Jamali to quit his post, Pakistan's Opposition parties have said that his resignation has pushed the nation into the "worst Constitutional crisis".

Islamic alliance Muttahida Majlis-e Amal (MMA) accused President Pervez Musharraf of prevailing on reluctant Prime Minister to resign and said Jamali's resignation was a "conspiracy" against the budding democracy in the country and a "dangerous threat" to national security.

Qazi Hussain, acting President of MMA which last year helped Musharraf to get his controversial constitutional amendments ratified by Parliament after he promised to quit the powerful post of Chief of Army by the end of this year, said Jamali's tenure showed that there was "one man rule" in the country and the elected Prime Minister carried no weight. "Nowhere in the world an outgoing Prime Minister nominates his successor and a senior minister, which shows that it is part of a big game whose strings are being pulled from somewhere else," Hussain, who is also the leader of the Jamat-e-Islami, said.

He said Jamali's resignation has pushed the country into the "worst constitutional crisis."

Amin Fahim, senior leader of Pakistan People's Party (PPP) headed by self-exiled former Prime Minister Benazir Bhutto, said "the dictatorial setup could not see any political Government to continue for more than two years so it has destabilised Jamali Government."
