The meeting, which was scheduled to take place at Sunbird Mount Soche Hotel, was shifted to MEC offices at the eleventh hour.
According to PAC executive director Robert Phiri, the meeting was shifted to the MEC offices amid electoral body's security concerns.
PAC has already met President Peter Mutharika, Human Rights Defenders Coalition (HRDC), UTM Party leader Saulos Chilima and Malawi Congress Party (MCP) leader Lazarus Chakwera.
Since MEC declared Mutharika winner of the May 21 presidential poll with 1 940 740 votes, representing 38.8 percent, the political temperature has risen, with nationwide demonstrations which in some cases have been marred by looting and violence.
Results MEC announced put Chakwera on second position with 1 781 740 votes, representing 35.41 percent and Chilima came third, ahead of four other aspirants, with 1 018 369 votes, representing 20.24 percent.
Chilima and Chakwera have since filed a petition in the Constitutional Court seeking nullification of the presidential election results. They cite alleged flaws in the results management process as a key factor for their case.
On the other hand, HRDC has been organising nationwide demonstrations to force Ansah to resign for allegedly presiding over a flawed electoral process.
PAC’s mediation team comprises members from Episcopal Conference of Malawi (ECM), Evangelical Association of Malawi (EAM), Quadria Muslim Association of Malawi (Qmam) and Malawi Council of Churches.
PAC was formed in 1992 during the country’s political transition from one-party to multiparty system of government.
