DUBAI: Iran's hardline lawmakers plan to summon the president for questioning, a move that could ultimately lead to impeachment, media reported on Monday, amid growing discontent over the government's economic policies.

Iranians' daily struggle to make ends meet has become harder since the reimposition of U.S. sanctions in 2018, and the economy has been further damaged by rising inflation, growing unemployment, a slump in the rial and the coronavirus crisis.

A motion to question President Hassan Rouhani was signed by 120 lawmakers out of 290 and handed to the presiding board of the assembly, Iran's semi-official Tasnim news agency reported. To take effect, the motion must be passed to the president by the presiding board.

However, analysts say the board might hold back from issuing the summons, mindful that Supreme Leader Ayatollah Ali Khamenei, Iran's top authority, has called for unity among the branches of authority at a time when Iran faces mounting U.S. pressure.

A move by parliament to question Rouhani's predecessor was blocked by a rare intervention by Khamenei.

"The lawmakers have various questions for the president, including the reasons behind the foreign exchange market crisis as well as the high prices of basic goods and basic necessities of the people today," Tasnim quoted Tehran lawmaker Eqbal Shakeri as saying.

Defying central bank attempts to revive its value, Iran's rial currency has continued to fall against the U.S. dollar on the unofficial market since April.

First elected in a landslide in 2013 and re-elected in 2017, Rouhani opened the door to nuclear diplomacy with six major powers that led to a 2015 nuclear deal, under which Iran agreed to curb its sensitive nuclear work in return for the easing of sanctions.

But hardliners opposed to the West were always lukewarm about the agreement, and they fiercely criticised Rouhani when U.S. President Donald Trump quit the deal in 2018 and reimposed sanctions that have choked Iran's vital oil exports.
