TEHRAN, Young Journalists Club (YJC) - Voting began across 85,000 booths at 8 a.m. local time and will close at 6 p.m. on Wednesday.
The final outcome is expected to be announced within 24 hours after the polling, but preliminary results will be out late at night.
A tight race has been underway between the party of jailed-ousted prime minister Nawaz Sharif — the Pakistan Muslim League-Nawaz (PML-N), and that of former star cricketer Imran Khan — Pakistan Tehreek-e-Insaf (PTI).
The latest polls suggest that the former cricket hero is leading the race to become Pakistan's next prime minister.
“Let's test Imran as we have been testing others for the last several decades," said a 22-year-old voter, who cast his ballot for Khan's party in the city of Lahore in Punjab.
Sharif, 68, who was imprisoned on corruption-related charges earlier this month, will be watching this election from behind bars. He was removed from office by the Supreme Court last year.
He returned from London earlier this month, along with his daughter Maryam. Both, however, were taken into custody. Sharif faces 10 years in jail and his daughter will be imprisoned for seven years..
In the event of PML-N’s victory, Shrif’s brother and former Punjab Chief Minister, Shahbaz would be the next prime minister
Pakistan’s ‘dirtiest election’
The vote, however, has been dubbed the “dirtiest election” due to allegations of widespread pre-poll rigging by the armed forces, with Khan believed to be the beneficiary.
A judge in the High Court of Islamabad appeared to back up the allegations on Sunday, claiming that the military Inter-Services Intelligence (ISI) had been interfering in the judiciary.
The powerful military, whose ruling fell out in 2007 by the outgoing party of Sharif, however, denies any involvement.
But the independent Human Rights Commission of Pakistan (HRCP) has said there are "ample grounds to doubt" the legitimacy of the elections and criticized "blatant, aggressive and unabashed attempts to manipulate the outcome."
The run-up to the elections has seen a massive crackdown on the media with many journalists saying they have suffered intimidation for their reporting.
The final weeks of the campaign season were marred by a string of bloody militant attacks that left more than 180 people dead -- three of them candidates.
Up to 800,000 police and military forces have been stationed across the country to secure tens of thousands of polling stations.
