Anoosheh Ashoori, a British-Iranian man detained in Iran, says the UK is not doing enough to save him.

In a phone recording given to Sky News, Ashoori says he is acting out of desperation and his family have released the message in an attempt to prompt some action towards securing his release.

The south London retiree has been detained in an Iranian jail for three and a half years.
