Iran's parliament on Sunday overwhelmingly approved the outline of a bill that, if passed, would impose strict conditions on any nuclear deal with world powers, Reuters reported.

The draft bill must still pass through parliament and then the Guardian Council, an unelected body close to Supreme Leader Ayatollah Ali Khamenei, before becoming law, the report noted.

The draft was approved by 199 of the 213 lawmakers present, underlining significant domestic pressure on Iran's negotiating team.

The bill would require sanctions to be lifted immediately and bar UN inspectors from military sites, a position that the United States and France have said they will not accept.

"Access to all military, security and sensitive non-nuclear sites, as well as scientists, is prohibited," the draft document said. "The complete lifting of sanctions ... must take place on the day Iran begins implementing its obligations."

Parliament Speaker Ali Larijani responded to the bill by warning lawmakers not to over-reach, reminding them of Khamenei's influence over the Supreme National Security Council.

"The Supreme National Security Council is under the supervision of the Supreme Leader, and we must not bind his hands on this issue," Larijani said, according to the report.

Khamenei has publicly placed his trust in the negotiating team and cautiously supported a deal, but has also ruled out inspections of military sites and interviews with scientists.

Iranian lawmakers, critical of President Hassan Rouhani for supporting talks with the West, have already attempted to use legislation to thwart a deal.

In March, an overwhelming majority of 260 out of 290 Iranian parliament members passed a proposal designed to strengthen the regime's policy regarding the nuclear talks with world powers.

The proposal’s three clauses included a demand for a removal of all sanctions against Iran, a call for a preservation of Iran's nuclear infrastructure and rights to develop nuclear power, and a restarting of Iran’s uranium enrichment if any of the obligations of the nuclear deal are breached.

Iranian officials have continuously accused the West of imposing excessive demands on the Islamic Republic and have warned the six powers against doing so.
