John McCarthy talks to those who by accident or design, feel they live outside mainstream British society. Today he talks to Rafi, who fled to this country from Afghanistan in 2011, after working as an interpreter for the allied forces. Rafi explains how he took on the role in the hope of improving relations in his country but in fact it left him isolated from his home community and the people he worked for. Threats from the Taliban caused him to flee his homeland and to seek asylum here. After eighteen months of isolation in this country, he has now gained refugee status and can look for work but he explains the loneliness he feels living on the outside and away from his home, his friends and family.
