British-Iranian dual nationals should not travel to Iran, the Foreign Office has said.
The Foreign Office changed its travel advice because of the Iranian government’s “continued arbitrary detention and mistreatment of dual nationals”.
The advice has also changed because of Iranian citizen links with UK institutions.
British nationals, particularly dual nations, face an “unacceptably higher risk” of arbitrary detention and mistreatment than nationals of other countries, the FCO added.
Foreign Secretary Jeremy Hunt said:”Dual nationals face an intolerable risk of mistreatment if they visit Iran. Despite the UK providing repeated opportunities to resolve this issue, the Iranian regime’s conduct has worsened.
“Having exhausted all other options, I must now advise all British-Iranian dual nationals against travelling to Iran. The dangers they face include arbitrary detention and lack of access to basic legal rights, as we have seen in the case of Nazanin Zaghari-Ratcliffe, who has been separated from her family since 2016.
“Regrettably, I must also offer a message of caution to Iranian nationals resident in the UK – but who return to visit family and friends – especially where the Iranian government may perceive them to have personal links to UK institutions or the British government.”
The Iranian government does not recognise dual nationality, and the FCO has limited capacity to provide consular support to jailed British-Iranian nationals.
