"If they make an effort to deprive the Iranian nation of their undeniable right for peaceful nuclear technology ... the parliament will reconsider the nature of its relationship with the International Atomic Energy Agency (IAEA)," Adel told the state television.

He noted that a bill to suspend the IAEA's inspections of Iran's nuclear sites has already been passed by the parliament’s national security and foreign affairs committee.

"If Iran comes under pressure, we will have no other choice but to bring this bill before parliament for debate," Adel said.

The UN Security Council president for December, Nassir Abdulaziz Al-Nasser of Qatar, said on Friday that the council is expected to put the draft resolution to the vote on Saturday morning.

The draft, originally set to vote on Friday, is sponsored by Britain, France and Germany. It would slap a ban on imports and exports of materials and technology relating to uranium enrichment, reprocessing and heavy-water reactors, as well as ballistic missile delivery systems.

However, the Europeans have made a number of changes to the draft to meet Russian concerns, including watering down a contentious proposal for a travel ban on some Iranian officials directly linked to Iran's nuclear and ballistic missile programs.
