Nazanin Zaghari-Ratcliffe has been sentenced to a further year in prison and a one-year travel ban after being found guilty of joining a London protest twelve years ago and speaking to the BBC Persian service. Her husband said she has not been taken to prison yet; she plans to appeal against the sentence. Mr Ratcliffe said, ‘The threat is there, and it is bigger than we were fearing. I think the worst case got a bit closer.’ He maintains that his wife was imprisoned as leverage for a debt owed by the UK over its failure to deliver tanks to Iran in 1979; also, her case may be caught up with the negotiations over limiting Iran's nuclear material enrichment. Her sentence may indicate that the Iranian regime is unhappy with the negotiations taking place in Vienna. Things could get worse for Mrs Zaghari-Ratcliffe and other jailed dual nationals.
