ROUHANI UNDER ATTACK FROM ALL SIDES

TEHRAN: Iran's President Hassan Rouhani is clinging to power but finds himself under attack from all sides -- conservatives, reformists and the street -- as he prepares for a grilling in parliament on Tuesday.

The US withdrawal from the 2015 nuclear deal between Tehran and world powers and Washington's reimposition of sanctions have already battered the Iranian economy, and critics say it has exposed the failures of Rouhani's five years in power.

For the first time, lawmakers have summoned Rouhani to parliament to face questions over the collapsing value of the Iranian currency, over stubbornly high unemployment and corruption.

Lawmakers have already impeached his labour and economy ministers this month, and are seeking further scalps.

They have the power to impeach Rouhani himself, though he is protected by the fact that Iran's supreme leader Ayatollah Ali Khamenei said he should see out his term to 2021, despite his own harsh criticisms of the president's policies.

Despite his dim prospects, Rouhani still has the backing of moderate conservatives, including powerful parliament speaker Ali Larijani.

But many in the hardline establishment opposed his negotiations with the West and feel vindicated by the unravelling of the nuclear deal.

They have led the charge against Rouhani's cabinet, and were on Monday seeking enough votes for impeachment proceedings against his industry and transportation ministers. "The best outcome for them is a lame duck president, as their chances will go up for (the next election) in 2021," said political journalist Fereshteh Sadeghi.

As for the reformist faction, it was key to Rouhani's election successes in 2013 and 2017, seeing him as its best option after the movement was suppressed in the wake of mass protests in 2009. But Rouhani has failed to deliver on his promises of easing civil liberties, particularly his vow to release political prisoners and reduce censorship.

Reformists now fear being tarnished by their association with Rouhani and some have broken ranks to slam the government's performance.

"What have we done with this nation? We made them miserable and wretched," said reformist MP Elias Hazrati as he voted in favour of impeaching Economy Minister Masoud Karbasian on Sunday.

"No one believes Rouhani will reform anything anymore. He was just a tool for the system, appearing to address people's demands for change without really changing anything," said Clement Therme, Iran research fellow for the International Institute for Strategic Studies (IISS).
