Half of the one million migrant workers that have come to the UK since their countries joined the EU in 2004 have already gone home, according to a new report.

The number of workers arriving from Poland and other eastern/central European countries is likely to fall in the coming months and years as economic conditions improve in their own countries, according to a report by the Institute for Public Policy Research (IPPR) think-tank. More of those currently in the UK are likely to return home too, it says.
