There was a rare display of unity in the Commons chamber this afternoon when Liz Truss gave a statement on the release of Nazanin Zaghari-Ratcliffe. While Labour deputy leader Angela Rayner went on the attack at PMQs, asking whether Johnson’s comments when he was Foreign Secretary had made things worse, there was a far more conciliatory tone in the Commons when the Foreign Secretary updated MPs on the 43-year-old British-Iranian dual national’s safe return, after being detained in Iran for more than five years on charges of plotting to overthrow the Tehran government.
