Iran's veteran envoy to the U.N. nuclear agency, Ali Asghar Soltanieh, is expected to leave his post soon but there is no word yet on who will replace him, diplomatic sources said on Wednesday.
If confirmed, it would come less than a week after the newIranian president, Hassan Rouhani, a relative moderate, appointed a pragmatist to headIran's atomic energy organisation.
Rouhani has pledged to improveIran's ties with the outside world and ease stringent international sanctions on the Islamic Republic over its nuclear programme.
There was no immediate comment fromIran's mission to the U.N. International Atomic Energy Agency (IAEA).
The IAEA is investigating allegations thatIranhas carried out research relevant for the development of nuclear weapons, a charge the country denies. Western diplomats have accusedIranof stonewalling the IAEA's investigation.
