TEHRAN (FNA)- Spokesman of Iran's Guardian Council Nejatollah Ebrahimian reiterated that the Additional Protocol to the Non-Proliferation Treaty (NPT) can be endorsed and implemented only if the parliament accepts it.

"The Lausanne agreement (nuclear statement issued by Iran and the world powers on April 2) says that Iran should accept the Additional Protocol; but acceptance of the Additional Protocol very clearly needs the parliament's approval," Ebrahimian told FNA on Sunday.

"No doubt, the authority for accepting and implementing the Additional Protocol by the Islamic Republic of Iran's government is vested on the parliament and needs its approval," he added.

His remarks came after Chairman of the parliament's National Security and Foreign Policy Commission Alaeddin Boroujerdi said early April that many lawmakers in the legislative body were strongly opposed to the endorsement of the Additional Protocol to the NPT by Iran, making its approval rather unlikely.

"There are opposing views at the parliament over accepting and implementing the Additional Protocol and the path is not leveled for its approval," Boroujerdi told reporters in Tehran last month.

Yet, he underlined that should there be a need to exercise the protocol in Iran, it will first need to receive the parliament's approval, and said, "If you remember, 10 years ago when the Iranian government implemented the Protocol voluntarily, the parliament announced that if Tehran's nuclear case were referred to the Security Council from the International Atomic Energy Agency (IAEA)'s Board of Governors, the legislature would require the government to stop its implementation, and it did."

Boroujerdi also warned that the parliament precisely monitors the developments following the nuclear agreement between Iran and the Group 5+1 (the US, Russia, China, Britain and France plus Germany) and has ratified the urgency of a bill that would require the government to shift its path if the western side breaches its undertakings.

Also reports on Saturday said that the Iranian parliamentarians, in reaction to the US Senate's bill, were studying the double-urgency of a bill that would increase their supervision on any possible nuclear agreement between Tehran and the world powers.

"The US Senate's recent measure showed that the US is after a escape goat to shun implementing its undertakings under a possible nuclear deal," Rapporteur of the parliament's National Security and Foreign Policy Commission Seyed Hossein Naqavi Hosseini said yesterday.

Referring to the Iranian parliamentarians' bill that would boost the legislature's supervision on a possible nuclear deal between Tehran and the G5+1, he said, "The bill has been compiled based on Articles 77 and 125 of the Constitution and will be studied at the parliament in the near future."

Naqavi Hosseini said that the Americans' past record showed that they had always pursued dual-track and deceptive policies, while they had not been a trustworthy partner during the nuclear talks with Iran either.

The parliament's decision was announced after the US Senate on Thursday advanced a legislation that would allow the Congress to review a nuclear deal between world powers and Iran.

After nine days of hard work in Lausanne, Switzerland, Iran and the G5+1 reached an understanding on April 2 which laid the ground for them to start drafting the final nuclear deal over Tehran's nuclear energy program ahead of a July 1 deadline.

Reading out a joint statement at a press conference with EU foreign policy chief Federica Mogherini in Lausanne on April 2, Iranian Foreign Minister Mohammad Javad Zarif said according to the agreement, all the US, EU and UN Security Council sanctions against Iran would be lifted under the final deal.

The delegations of the seven nations are now drafting the final deal.
