The UK has been the top destination for immigrants from the 10 new European Union member states since the trade bloc expanded last year, a report says. Germany's DIW Institute estimates that up to 150,000 people have migrated to the older members since May 2004. Economic research group DIW found that more than 50,000 people had made their way to the UK over the past 12 months. However, that figure is much lower than other estimates and the UK government puts the number closer to 130,000.
