British Foreign Secretary David Miliband said Monday that Britain, Russia, and their international partners want a “prompt response” from Iran on a uranium enrichment proposal.

At a joint news conference with Russian Foreign Minister Sergei Lavrov in Moscow, Miliband said, “We both want to see a prompt response from the Iranian regime in respect of the Tehran research reactor proposal.”

He added, “We both want to see a positive response to the offer that was agreed by the E3 +3…in May 2008.”

The E3 + 3 refers to the five permanent members of the UN Security Council–Britain, China, France, Russia, and the United States–plus Germany.

Miliband said that Mohamed ElBaradei, the director-general of the International Atomic Energy Agency–the UN’s nuclear watchdog–has given Iran another 48 hours “to come up with a serious response.”

He added, “That’s what we all want to see.”

Iran said last week that it tentatively agreed to the IAEA’s proposal, but then proposed its own conditions.
