The UK government has known for many years that if it paid a £400m debt to Iran it was likely to lead to the release of Nazanin Zaghari-Ratcliffe, the former Foreign Office minister Alistair Burt has said in a letter to the foreign affairs select committee.
Burt, a Tory MP until 2019, is calling for the committee to launch an inquiry into why the debt was not paid and into who – either in the governments of the UK or the US – resisted making the payment.
