Lebanon's Hariri says forming new government is 'not impossible' amid rising concerns

Efforts to form a new Lebanese government after months of negotiation remain "on their way to a solution", prime minister-designate Saad al-Hariri said on Monday.

Last week President Michel Aoun said a government would be formed "very soon" and a government source said it would be agreed during the weekend, but press reports on Monday cited senior politicians saying problems persisted.

Parties have been jostling since May's parliament election over ministerial positions in a new national unity government, but the political uncertainty has contributed to fears that Lebanon faces a looming economic crisis.

"Contacts continue to form a government and the issue is not impossible, as some are trying to suggest," Hariri said in televised comments to reporters.

Lebanon has one of the world's most indebted governments, owing about 150 per cent of gross domestic product, and the International Monetary Fund warned early this year that Beirut must urgently undertake fiscal reforms.

President Aoun said in a Twitter post on Monday that circumstances required a rapid formation of the government.
