The report pointed out that professionals such as doctors, academics, executives and scientists have left Britain in the last 20 years for better job prospects, better climate and a good lifestyle. As was reported by telegraph.co.uk, these professionals leave for countries such as Australia, America and Canada. Business leaders also felt that the high 'income tax' might be one of the main reasons for the heavy number of immigration.

The other reasons for the change of country, as cited by the report is cost of living and the slow economic recovery. The report also pointed out that around 149,000 British citizens emigrated last year, and 4.7 million now live overseas and from the past this figure has risen sharply.

It was seen that in 2010, 48 percent of British emigrants came from professional backgrounds as compared to 37 percent in 1991. The report also underlined the fact that people with major corporations who went to New York actually returned after 2-3 years but British scientists emigrating to Boston to work in pharmaceutical and biotechnology companies stayed in the US for an average of 12 years.

The income tax rate of Britain is one of the highest and people living abroad also say that they move from their homeland for better living cost. The other part of the story is that people coming to the UK from other parts of Europe also do not stay as opposed to immigrants who come from poorer countries, adding to UK's population. Thus many feel that the government must be very strict to the immigrants who want to settle in the country.
