BRITAIN is preparing to pay a long standing £450m debt to Iran that will help free imprisoned mum Nazanin Zaghari-Ratcliffe.
Boris Johnson and Chancellor Philip Hammond quietly authorised government lawyers to finally settle the 38 year-long dispute over a tank deal.
An international court ordered the UK to reimburse Teheran after the MoD reneged on a deal to sell Chieftan tanks to Iran in 1979, but still kept Iran’s cash.
As The Sun revealed yesterday, Iranian regime hardliners have told ministers they expect the debt to be settled as part of a shopping list of demands before Nazanin is freed.
The traumatised 38-year-old’s husband Richard Ratcliffe also heaped pressure on the Foreign Secretary yesterday to come good on the huge debt.
Speaking after his first meeting with Boris, Mr Ratcliffe said of the tank deal row: “It is important that the UK honours its international legal obligations, so that Iran can honour its legal obligations.
“They are separate things, but it is good for the atmosphere if they are all served.”
Treasury and Foreign Office officials are working on a way around ongoing UN sanctions on military equipment, overseen by the EU, that currently forbid the payment.
The money is already being held by the High Court on behalf of the Government, after the Hague’s Permanent Court of Arbitration ruled in favour of Iran in 2001.
But senior diplomats insisted last night the payment would not be a ransom bill, as ongoing talks with Teheran about it as entirely separate to efforts made to free Nazanin.
Mrs Zaghari-Ratcliffe has been locked up since April 2016 on trumped up propaganda charges.
A government spokeswoman said: “This is a long standing case and relates to contracts signed over 40 years ago with the pre-revolution Iranian regime.
“Funding to settle the debt was paid to the high court by the Treasury in 2002.
“Iran’s Ministry of Defence remains subject to EU sanctions.
“It is wrong to link a completely separate debt issue with any other aspect of our bilateral relationship with Iran.”
Boris pledged to “leave no stone unturned” to free Nazanin as he met Mr Ratcliffe in the Foreign Office yesterday morning.
He agreed to consider giving her diplomatic protection status in a bid to demand her release.
The Foreign Secretary also pledged to look at Mr Ratcliffe’s second request, to be able to accompany Boris to Teheran next month.
Mr Ratcliffe – who has been denied a visa to see his wife and three year-old daughter for the last 18 months – dubbed the meeting “positive and constructive”.
He also said he was no longer angry with Boris for saying Nazanin was in Iran to “train journalists” – a gaffe leaped on by Iran to slap an extra five years on her sentences.
