A senior State Department official did not give a reason for Mr Nephew's change of role but told Reuters that personnel moves were "very common" a year into the administration. <i>The Wall Street Journal</i> earlier reported that Mr Nephew left after differences of opinion in the US negotiating team on the Iran nuclear deal. His appointment as deputy to<a href="https://www.thenationalnews.com/world/the-americas/who-is-joe-biden-s-iran-envoy-robert-malley-1.1156065" target="_blank"> Mr Malley</a>, who was criticised for being too soft on Iran, had been an attempt to strike a balance on the team, with US Secretary of State Antony Blinken pushing for diversity of views on the Iran issue, US sources told <i>The National.</i> This stance has delayed several appointments but Mr Nephew was an early pick for the job because of his expertise and close relationship with the Biden transition team. <i>Agencies contributed to this reporting</i>
