Michael Portillo visits a busy charity health clinic recently set up in the Athens suburb of Perama where unemployment has risen to 80% and few can afford to pay for health care.
The charity Doctors of the World mostly works in the developing world but is experiencing strong demand in Greece as a result of the impact of the economic crisis, which has led to cuts in government services including health care and increased charges.
