"New rifts will soon surface in Saudi Arabia's social and political structures due to the absence of democratic freedoms in the kingdom," member of the parliament's National Security and Foreign Policy Commission Abbasali Mansouri Arani said.
"Given the structure of the ruling system, we will witness rifts in Saudi Arabia's ruling system and social strata in the near future," he added.
The senior Iranian lawmaker called on Al Saud government to implement fundamental changes in its ruling system in a bid to survive a popular revolution that will lead to its downfall as was the case with the former regimes in Egypt and Libya.
There have been numerous demonstrations in the oil-rich Eastern Province since February 2011, with protestors primarily calling for political reform and an end to widespread discrimination.
Anti-government protests intensified, however, since November 2011, when security forces opened fire on protestors in Qatif, killing five people and leaving scores more injured.
In October 2012, Amnesty International called on Saudi authorities to stop using excessive force against the protestors.
Saudi forces have also arrested dozens of people including prominent Shiite cleric Sheikh Nemr al-Nemr.
According to Human Rights Watch, the Saudi regime "routinely represses expression critical of the government".
Also in October, the Saudi Interior Ministry warned the public against staging demonstrations in support of the prisoners in the kingdom and pledged to deal "firmly" with those participating in such protest rallies.
