The upcoming parliamentary elections will apparently be held under a new law based on proportional representation, media reports said on Sunday.

"The only remaining obstacle is the demand to move some Christian seats across some districts,” al-Mustaqbal newspaper said.

“It has become known that President Michel Aoun in agreement with Prime Minister Saad Hariri is inclined to sign a decree opening an extraordinary legislative session... and Speaker Nabih Berri yesterday announced the postponement of Monday's session to June 5 in a step that observers say is aimed at confirming the optimism that is engulfing the electoral discussions,” the daily added.

Al-Mustaqbal said the last hours witnessed an agreement in principle on the format of the new law.

“The 15-electorate format is making headway and an agreement has been reached on counting votes for preferred candidates in each of the current 26 administrative districts,” the daily added.

It said the electoral districts will be three in the Bekaa, three in the South, four in Mount Lebanon, three in the North and two in Beirut.
