Lebanon was to hold talks Monday to designate a new premier who will make the third attempt within a year to form a government amid deepening political and economic turmoil.
The country has been without a fully functioning government since then-prime minister Hassan Diab resigned in the wake of the Beirut port explosion that killed more than 200 people last August.
Despite an economic crisis branded by the World Bank as one of the world's worst since the mid-19th century, political squabbling has repeatedly thwarted progress, with two designated premiers failing to form a cabinet since then.
On Monday, consultations between President Michel Aoun and parliamentary blocs aim to find a replacement for Saad Hariri, who quit as PM-designate on July 15 after nine months of political horse-trading failed to produce a new cabinet.
Talks were to begin in the presidential palace at 10:30 am (0730 GMT) and will run until the afternoon with a final pick announced by the end of the day, said the official National News Agency.
According to local media reports, billionaire businessman and two-time premier Najib Mikati is the most likely choice.
Three of Lebanon's former prime ministers -- Hariri, Fouad Siniora and Tamam Salam -- on Thursday said they would endorse Mikati's candidacy.
If selected, the 65-year-old political veteran will be expected to deliver a lineup that satisfies political leaders jostling for cabinet shares and ministerial portfolios.
It could take months before an actual government is formed, but crisis-hit Lebanon, grappling with soaring poverty, a plummeting currency and shortages of basic items from medicine to fuel, can ill afford any delays.
International donors led by former colonial power France have pledged millions of dollars in humanitarian aid, but conditioned it on Lebanon installing a government capable of tackling corruption.
But even as international pressure mounted, with threats of European Union sanctions against them, Lebanese politicians have failed to make any serious progress.
France this month said it would host an aid conference on August 4 to "respond to the needs of the Lebanese, whose situation is deteriorating every day".
The date of the conference coincides with the first anniversary of the port blast which is widely blamed on decades of negligence by the country's ruling class.
