This 75% number does not say clearly when these cases were commenced or how many there were. If the Refugee Council were dealing only with genuine refugees, then I don't think anyone could complain. However, the recent problem with many economic migrants is not mentioned specifically, and, I would be concerned that migrants, that have probably paid big money to get here, are being given the same chance to remain in the UK as genuine refugees are.
I haven't heard of many repatriations to Saharan Africa, the Middle East or further afield. Have you?
