Up to 250 people have already been killed in the ongoing protests, with demonstrators accusing security forces of violence and heavy-handedness.
In a televised address, President Barham Salih said the PM had “agreed” to submit his resignation — but said he would only resign if a replacement was decided upon to avoid creating a “constitutional vacuum.”
Salih also vowed Monday to deliver an early election in response to the growing protests after a new electoral law has passed. He said he expected a new electoral bill to be introduced to the parliament next week.
Protesters are demanding an overhaul of the country’s political system which was implemented following the 2003 US invasion.
Abdul Mahdi’s agreement to step down comes as Lebanese PM Saad al-Hariri tendered his own resignation earlier this week following large scale anti-government protests over corruption and economic turmoil.
