England 's population is up 565,000 in the past three years because of a fresh influx of migrants , experts said yesterday . The migrant population in England is estimated to have increased by more than half a million in three years , research from the University of Oxford has revealed . Around two thirds of the 565,000 migrants thought to have come to the country between 2011 and 2014 were born in other EU countries , the study by the university 's Migration Observatory said . Today the former head of the European Commission taunted David Cameron over this issue and said it was 'impossible ' for Britain to reverse the trend . Scroll down for video . Picture of Britain : England 's population is up 565,000 in three years just because migrants . Here is a regional picture of the total foreign population of England and the percentage it has risen in since 2011 . Jose Manuel Barroso said : ‘ When you have 28 countries it will be impossible to say , let ’ s say , the French can come to Britain to work in the City but the Poles can not come to Britain – this is not possible . This will be a violation of the principles of no discrimination . ‘ Having said that , the European Union is very much aware that there is the abuse of social benefits . If you have not the means to be in the country , you can not go there just to benefit from the social security . ‘ But you have the right , if you are a citizen of a European country to go to another country to establish there. ’ Poland is trying to call its skilled workers home from Britain . Ambassador Witold Sobkow said it can not afford to lose its best young people and wants to persuade them to return . The Polish authorities also hope EU freedom of movement rules will encourage other Europeans to look for jobs in the country , boosting its economy . Mr Sobkow said efforts were under way to bring back some of the millions of young Poles who left for Britain and after Poland joined the EU in 2004 . He told BBC Radio Four : ‘ We have a special programme called Returns and the government is trying to attract these people back home . ‘ We are worried that we may lose some well-educated people , and also skilled workers , because we need them. ’ But he added : ‘ We have other nationalities in Poland ... so this is a kind of free movement of brains. ’ Plea : Witold Sobkow . He said as long as the principle of freedom of movement is not called into question , a deal can be reached to restrict migrants ’ benefits . The majority moved to London and the south-east but the north-east and Yorkshire and Humber saw the biggest percentage increases , figures show . Every council area of England has seen an increased migrant population , it was said . Researchers , who stressed that the numbers are estimates , said the projections give a more up-to-date picture of the migrant populations across England than the 2011 census . It came as the Institute for Fiscal Studies found that rising number of migrants has led to council services spending by being cut in half - and those with highest migration numbers were hit hardest . Official estimates on population are expected in June from the Office for National Statistics . The greatest increase in the number of foreign-born residents has been in the capital . Almost 200,000 more migrants were estimated to live in London last year , compared to 2011 . The South East saw the second-highest rise of 79,000 , while the smallest increase was in the North East where an extra 26,000 migrants are thought to have arrived since 2011 . Madeleine Sumption , Director of the Migration Observatory , said the study was done to provide more insight ahead of the general election . 'These data show how different local experiences of migration have been across the UK , ' she said . 'There are large variations in the size of migrant populations , as well as the share that come from EU countries . Figures : The study shows how all regions have seen thousands more migrants from within the EU since 2011 . Embarrassing : Despite pledges from David Cameron thousands of migrants from outside the EU also came to England . 'We have undertaken this analysis to provide a resource for anyone looking to understand local demographics of migration in the run-up to the general election . ' The news piles more pressure on David Cameron , whose promise to curb immigration has been shattered , . Last week it emerged annual net migration – the measure of how many people have come into Britain minus those who have left – has reached nearly 300,000 - a record . When he took power in 2010 Mr Cameron pledged to bring this politically sensitive figure below 100,000 . A total of 624,000 people migrated to Britain in the 12 months up to last September while 327,000 left . The inflow is up 94,000 on the year before . Official figures : Last year 300,000 migrants arrived in Britain , with 190,000 of them travelled from outside the EU . Net migration from the EU hit 162,000 in the year ending September 2014 , up from 130,000 in the previous year . A total of 37,000 Romanian and Bulgarian arrived in the UK , up from 24,000 in the previous 12 months .
New Oxford research reveals every region has seen increase in migrants . Of the estimated 565,000 increase a third came from outside the EU . Majority of England 's newest population went to London and south-east . But north-east , Cameron and Humber say largest percentage increases . Prime Minister had promised voters to cut net migration : 'No ifs . No buts ' Institute for Fiscal Studies says migration causes cuts to council spending .
