Lebanon has been plunged deeper into crisis after Hezbollah and its allies thwarted a bid by their rivals to elect a top IMF official as president, sharpening sectarian tensions and underlining the dim hopes for reviving the crumbling state.

Four years since Lebanon slid into a financial meltdown that marks its worst crisis since the 1975-90 civil war, parliament failed for a 12th time to elect someone to fill the post reserved for a Maronite Christian under the country’s sectarian system.

MPs from the Iran-backed armed Shi’ite group Hezbollah and allies including the Shi’ite Amal Movement withdrew from the session to obstruct a bid by the main Christian parties to elect IMF official Jihad Azour.

The stand-off has opened up a sectarian fault line, with one of Hezbollah’s main Christian allies – Gebran Bassil – lining up behind the bid to elect Mr Azour, alongside anti-Hezbollah Christian factions.

Mr Azour, the IMF’s Middle East Director and an ex-finance minister, won the support of 59 of parliament’s 128 MPs in an initial vote, short of the two-thirds needed to win in the first round.

Suleiman Frangieh, backed by Hezbollah and its allies, got 51 votes.

Hezbollah and its allies then withdrew, denying the two-thirds quorum required for a second round of voting in which a candidate can win with the support of 65 MPs.

It leaves Lebanon with no immediate prospect of filling the presidency, which has been vacant since the term of the Hezbollah-allied president Michel Aoun ended in October.

Hezbollah, which says it is exercising its constitutional rights, is backing its close Christian ally Frangieh, a friend of Syrian President Bashar al-Assad who strongly supports Hezbollah’s right to possess weapons.

Hezbollah, which is designated as a terrorist group by the United States, has unleashed fierce rhetoric in its campaign against Mr Azour, describing him as a candidate of confrontation.

Lebanon’s Shi’ite Mufti Sheikh Ahmad Qabalan dialled up the attacks on Sunday against Mr Azour without naming him, accusing him of being backed by Israel and saying “a president with an American stamp will not be allowed”.

Mr Azour, 57, has said he wants to build national unity and implement reforms in a country mired in its deepest crisis since its 1975-90 civil war.

Mr Azour served as finance minister from 2005 to 2008, a period of political conflict pitting a government backed by the West and Saudi Arabia against opponents aligned with Damascus and led by Hezbollah.

He also enjoyed the support of Lebanon’s main Druze faction, the Progressive Socialist Party led by the Jumblatt family, and some Sunni MPs.
