Iran's chief negotiator with the West over Tehran's nuclear programme, Ali Larijani, has resigned.THIS IS A BAD SIGN. AHMADINEJAD AND KHAMEINI WILL NOT APPOINT ANYONE WHO WILL CHANGE POLICIES; THEY'LL APPOINT AN EVEN WORSE PERSON.
A government spokesman said Mr Larijani had repeatedly offered his resignation and President Mahmoud Ahmadinejad had finally accepted it.
Mr Larijani had differences with the president over how to proceed with the negotiations, correspondents say.
Western countries suspect Iran of trying to build nuclear weapons but Tehran says its programme is peaceful.
The spokesman, Gholam Hossein Elham, said a deputy foreign minister, Saeed Jalili, would replace Mr Larijani in time for a meeting on Tuesday with the European Union's foreign policy head Javier Solana.
The BBC's Jon Leyne, in Tehran, says Mr Larijani has had differences with President Ahmadinejad over how to proceed with negotiations over the country's nuclear programme.
Mr Larijani has favoured further negotiations with the West over Iran's uranium enrichment programme, as opposed to the president's more hard-line approach, our correspondent says.
