The vote passed on Thursday by 77 MPs but some, including members of Aoun’s Free Patriotic Movement (FPM), who have been against the earlier date, expressed concern around whether a quorum was achieved for a second vote regarding the voting of Lebanese living abroad
The elections were originally expected in May.
Gebran Bassil, FPM leader and son-in-law of Aoun, withdrew alongside his alliance from the session on the back of the dispute, ending the session for the day.
“We withdrew from the session because of a major constitutional violation,” he said after leaving.
The March 27 election date would give Prime Minister Najib Mikati’s government only a few months to try to secure an IMF recovery plan amid a deepening economic meltdown.
