"We do not consider this election to be the mandate of the public."
The Pakistan Peoples Party had earlier on Friday decided not to attend the conference, with a spokesperson saying its leadership will devise its own strategy regarding alleged poll irregularities.
In attendance at the MPC were Jamaat-i-Islami (JI) chief Senator Sirajul Haq, Sindh Governor Mohammad Zubair, Gilgit-Baltistan Chief Minister Hafeezur Rehman, Azad Jammu and Kashmir Prime Minister Raja Farooq Haider, Awami National Party chief Asfandyar Wali Khan, Qaumi Watan Party chairman Aftab Ahmad Khan Sherpao, National Party's Senator Mir Hasil Bizenjo and several MMA leaders.
PML-N leaders Shahid Khaqan Abbasi, Ayaz Sadiq, Marriyum Aurangzeb, Chaudhry Tanveer and Khurram Dastagir and Pak Sarzameen Party (PSP) leaders Mustafa Kamal, Raza Haroon and Waseem Ahmed also participated.
Interestingly, Muttahida Qaumi Movement (MQM-P) leader Farooq Sattar also showed up to the conference, despite reports that his party has agreed to join the Pakistan Tehreek-e-Insaf (PTI)-led government in the centre after a contact between PTI leader Jehangir Tareen and Khalid Maqbool Siddiqui.
Speaking at the MPC, Sattar alleged that the July 25 polls were "rigged massively" and the results were altered.
"Results of their choice were devised and the party of their choice was made to win," he claimed.
The MMA had on Thursday rejected the poll results outright, calling for declaring the entire electoral exercise "null and void".
The recently revived alliance of five religio-political parties suffered a drubbing in the elections and even its chief, Maulana Fazlur Rehman, and JI chief Sirajul Haq tasted defeat in their native constituencies.
The PML-N too had decided to take all major parties, including the PPP and obviously excluding the PTI, on board to formulate a joint strategy to take up the rigging issue that it believes has deprived it of majority in the coming National Assembly.
