Javier Solana, the European Union's foreign policy chief, yesterday disclosed elements of Iran's latest proposal to resolve the crisis over its nuclear programme while offering the possibility that the EU could accept a solution short of its original demands.

Since the latest round of negotiations ended inconclusively in London last Friday, Iran has warned that it was prepared to resume some nuclear enrichment-related activities. The EU and US say this would be regarded as a breech of Iran's agreed freeze of its nuclear programme and would lead to referral to the UN Security Council.
