This picture clarifies a few neglected points:
Since 2010 there has been a marked decline in non-EU net immigration. As a proportion of non-British immigration to the UK, it has dropped from 73% in June 2010 to 57% in June 2013. In the last year alone, it has fallen from 172,000 to 140,000.
Meanwhile, this year, net migration from the EU has gone up by 72,000 to 106,000.
But, as the chart above shows, the recent increase in net EU migration has come from the older, more established (and traditionally more wealthy) EU member states (the EU15), not the new member states from central and eastern Europe that joined in 2004 (the EU8).
