Sir Andrew Green, Chairman of Migration Watch UK, responding to an Institute of Public Policy Research (IPPR) press release, said "More immigrants settling in Britain is the last thing we need. Our population is increasing by a third of a million every year, mainly due to immigration. We will have to build the equivalent of the city of Birmingham every three years just to cope with this. The public are, rightly, deeply opposed to the present massive levels of immigration without encouraging yet more.
