A member of the Majlis presiding board said the “prolongation” of the talks between Iran and the major powers on a final deal to resolve the nuclear disputes is to the detriment of the economy. “The prolongation of the nuclear negotiations leads to the continuation of sanctions, economic recession and impedes nuclear progress,” Mohammad Dehqan told Mehr news agency on Sunday. He said it is one of the US negotiating tactics to prolong talks to be able to impose demands through exerting pressure.
