Fears for the lives of British-Iranian hostages held in Iran have been raised amid claims the Government is using them as "bargaining chips" for diplomatic negotiations.
Reports suggest the UK Government is collaborating with the United States to release UK and US hostages in Iran simultaneously.
Amnesty International has said it would be "disgraceful" if UK officials have agreed any kind of agreement with the US government to "soft pedal efforts" to bring the hostages home.
