Iran's President Mohammad Khatami said today that an agreement to suspend uranium enrichment and sign up to snap nuclear inspections will have to be submitted to parliament for approval.
"It will have to be presented to parliament. It is like all other agreements," he said.
The outcome of a vote on the agreement is uncertain because although parliament is dominated by pro-Khatami reformists, all legislation must go to hardline supervisory body the Guardian Council.
Iranian hardliners regard snap inspections as tantamount as allowing spies into the country.
Tehran agreed to the snap inspections and to freeze uranium enrichment on Tuesday in what three visiting European ministers hailed as a promising start to removing doubts about Iran's atomic aims.
British, French and German foreign ministers flew to Tehran to try to persuade Iran to comply with an October 31st UN deadline to prove it has no atomic bomb ambitions.
