Iran demanded on Saturday that the European Union submit proposals in a dispute over its nuclear programme by Aug. 1 rather than take a week longer. The European Union -- represented by Britain, France and Germany -- is due to offer Iran a limited package of economic and political incentives. In return, the EU wants Iran to agree to maintain indefinitely its suspension of uranium enrichment, nuclear fuel reprocessing and related activities. Ali Aghamohammadi, a spokesman for the Supreme National Security Council, said the parties had originally agreed an Aug. 1 deadline, and that ambassadors for the "EU Three" had asked for this to be extended by six days. "We reject any delay. We are expecting their proposals to be submitted on Aug. 1 and it should meet Iran's minimum expectations," he told Reuters.
