Iran's leadership has been discussing whether to replace Parliament Speaker Mohammad Bagher Ghalibaf as chief negotiator with Mohsen Rezaei, according to Al Jazeera's Tehran correspondent Resul Serdar Atas. There has been no official confirmation.
The report cuts against what Ghalibaf said on Wednesday. He told Al Jazeera there had been no change to Iran's negotiating team and that he remained in charge.
Atas also says some voices in Tehran argue Iran might take pre-emptive action if the status quo continues for a long time. That is his account of the debate, not an official statement.
In the same interview, Ghalibaf said Washington must "make and announce" a decision on Iran's latest proposal, Al Jazeera's live blog reports. This follows Tehran's rejection of a US plan to move its 60% enriched uranium stockpile to a third country. He also said:
"what stands in the way of an agreement is our lack of trust in the United States"
Iran International reports Ghalibaf said Iran is determined to end its prolonged state between war and peace with the US through sustained deterrence, potentially without negotiations. None of these claims has been independently checked.
