Zaghari-Ratcliffe and Anoosheh Ashoori could be free in days

Possible deal to release pair involves agreement by UK to repay 400m debt, according to Iranian sources

British Iranian dual nationals Nazanin Zaghari-Ratcliffe and Anoosheh Ashoori could be freed and allowed to return to London within days under a deal in which the UK agrees to repay a 400m debt and release an Iranian prisoner.

Zaghari-Ratcliffe has for months been at her parent's home in Tehran awaiting news of whether she would have to serve a further one-year sentence in Iran handed down on top of the five years she had already served.
