A junior British minister held talks with his Iranian counterpart in Tehran on Saturday, in a first visit by a U.K. minister since Washington’s withdrew from the Iranian nuclear deal. The meeting between Britain’s Junior Foreign Minister Alistair Burt and Iranian Deputy Foreign Minister Abbas Araghchi covered economic cooperation and mechanisms of financial and monetary dealings between the two countries after the U.S. withdrawal from the nuclear deal. Burt was also expected to discuss the cases of dual nationals detained in Iran as Britain seeks the release of Nazanin Zaghari-Ratcliffe, a project manager with the Thomson Reuters Foundation who was arrested in April 2016 at a Tehran airport and later convicted of plotting to overthrow Iran’s clerical establishment, a charge denied by her family and the Foundation.
