Iraq's highest Shiite authority, whose opinions carry great weight in the country, on Friday urged voters not to re-elect "corrupt" MPs during next week's national elections.

Abdel Mehdi al-Karbalai, the representative of Grand Ayatollah Ali Sistani, issued the call during weekly Friday prayers in the holy city of Karbala.

He said Iraqis who will vote in the May 12 polls should not re-elect candidates from among MPs and officials who have already held government jobs and proved to be "corrupt and failing".

Iraq is ranked the 12th most corrupt country in the world by Transparency International.

More than 24 million Iraqis are registered to elect 320 deputies from a field of around 7,000 candidates on May 12, with 71 seats reserved for the capital.

According to the electoral commission, only 20 percent of the candidates are newcomers.

Karbalai said voters should "avoid falling into the trap of those who want to fool you", including "those whom you have known" — a reference to outgoing MPs and other officials running in the polls.

Political analyst Aziz Jaber said Karbalai's remarks targeted "heads of lists who have held government jobs and MPs such as vice-presidents Nuri al-Maliki and Ayad Allawi".

Prime Minister Haider al-Abadi — accused by critics of failing to tackle rampant corruption in Iraq — heads one of the main lists and hopes to be re-elected.

Shiite religious parties have come to play a greater role in the years since the 2003 US-led invasion that toppled dictator Saddam Hussein.

Sistani, whose opinions are widely respected among Shiites, mobilised tens of thousands of men to join paramilitary units of the Hashed al-Shaabi, which played a crucial role in defeating the Islamic State group in Iraq.

Iraq journalist who threw shoes at Bush stands for parliament
Baghdad (AFP) May 5, 2018 –

The Iraqi journalist who grabbed headlines around the world by hurling his shoes at then US president George W. Bush is pitching for a seat in parliament at upcoming elections.

"My ambition is to throw all the thieving politicians in prison, make them regret what they have done and confiscate their wealth," Muntazer al-Zaidi, 39, told AFP ahead of the May 12 vote in his conflict-scarred homeland.

Zaidi shot to prominence in December 2008 when he leapt up at a farewell press conference Bush was holding in Baghdad and flung his shoes at the US leader.

While he narrowly missed hitting the man responsible for launching the invasion of Iraq, Zaidi was later jailed for assaulting a head of state and ended up serving nine months behind bars.

After his release Zaidi sought refuge in Lebanon, where he settled and had a daughter.

The protest against Bush saw him hailed as a hero by many around the Arab world, and he remains unrepentant as he pushes for office.

"I don't regret what I did, on the contrary, I just regret that at that moment I didn't have another pair of shoes," said Zaidi, who is running for an alliance between Shiite cleric Moqtada Sadr and communists.

Placed low down on the Marching Towards Reform list in Baghdad, it appears Zaidi has little chance of actually getting elected — but he remains defiant.

"It would not be an honour to have thieves as colleagues, and my objective is to take back money that has been stolen," he said, when asked if he feared becoming like other politicians reviled for graft.

Zaidi explained that he chose to represent Marching Towards Reform as he said it is independent and looking to shatter the country's sectarian divide.

As for his view on US involvement in Iraq — a decade after he took aim at Bush, he remains deeply opposed and wants Washington's troops out of the country.

He rejects the idea that the US military presence has helped Iraqi forces battle back the Islamic State group.

"The US favoured IS, how can you say that they want to get rid of them?" he asked.
