Migrants also make a significant contribution to the economies of their home states, the report says, with returning cash flow sometimes exceeding official development aid. It is estimated that migrant workers sent back more than $100bn (£55bn) to their countries of origin in 2004.

They are accused of depriving UK workers of jobs and taking advantage of the UK’s benefits system. However, the critics chose to ignore four facts:
