Iran's parliament passed a bill today obliging the government to safeguard the country's "nuclear rights and achievements," despite talks with global powers on curbing the Islamic republic's disputed atomic programme.
The measure was met by anger from President Hassan Rouhani's government, with a spokesman saying the draft law was unconstitutional as it contravened the country's defence and security policies.
The bill's adoption reflects tension between Rouhani, a moderate who aims to end Iran's diplomatic isolation, and a conservative-dominated legislature, where hardliners often dispute the worth of negotiations with the West.
The bill, which still has to be signed into law by Iran's Guardian Council, says the government must "preserve the country's nuclear rights and achievements" and states that lawmakers have to approve any deal that may be struck with the West.
Some 214 lawmakers out of 244 present supported it, with 10 against, six abstentions and the remainder not voting.
The vote came as hard bargaining over a final deal, due by June 30, was intensified by Britain and France, who reiterated that comprehensive inspections of Iran's nuclear facilities are essential compliance measures.
The bill allows inspections of nuclear sites but not military or sensitive non-nuclear establishments -- a stipulation likely to alarm Western powers given their longstanding suspicion that Iran seeks to develop an atomic bomb.
Rouhani's spokesman, Mohammad Bagher Nobakht, said: "This bill contradicts article 176 of the constitution. The issue of negotiations is in the sphere of the Supreme National Security Council... Not the government or the parliament."
His comments came despite the bill being watered down on Sunday, with the task of supervising a nuclear deal being given to the SNSC, a committee ultimately controlled by Iran's supreme leader Ayatollah Ali Khamenei.
Parliament had wanted the right to have oversight on any nuclear agreement.
Iran and the P5+1 powers -- Britain, China, France, Russia and the United States plus Germany -- agreed the outlines of the nuclear deal on April 2 after intensive talks went past a March 31 deadline.
But roadblocks remain on both the details of the agreement and opposition to its measures from both US and Iranian lawmakers.
In a measure similar to that taken in Tehran, President Barack Obama has given US lawmakers 30 days to review any nuclear deal.
