A Liberal Democrat MP has called for the immediate publication of a report that suggests that the effects of immigration is less than feared.
The report, compiled by a group of academics and immigration experts last year, has been withheld by the Government which fears that it would prove "politically controversial", the BBC's Newsnight reports.
The findings of the study reportedly reveal that the impact on British workers as a direct result of immigration is far lower than what the government claims.
Research from the Migration Advisory Committee has been used by the Home Secretary Theresa May previously as evidence for claiming that “for every additional 100 immigrants […] 23 British workers would not be employed”.
That figure, according to the study, is much lower, Newsnight said.
The figures suggested by the study have also been agreed on by the Home Office.
Liberal Democrat MP Julian Huppert told Newsnight the report should be published “as quickly as possible”.
"We have to have the right figures, so we can make the right decisions, so that we get the best people here to help our economy,” he said.
Shadow immigration minister David Hanson told the Independent: “The British people should have information made available to them so they can make a judgement about the impact of immigration on jobs.
“This should be done on the basis of fact, not more empty rhetoric or spin from the Government.”
The government has refused to comment on what it called an "internal" document.
Migrant entrepreneurs have set up one in seven UK companies, an investigation has found.
The news comes a day after new research revealed that companies owned by immigrants are responsible for creating a staggering 14% of all jobs in the small and medium enterprises (SME) sector.
The survey, by the Centre for Entrepreneurs and information experts DueDil, said near 500,000 people from more than 150 countries had moved to Britain to open businesses here.
The study found that significant numbers of businessmen and women migrated from countries such as India, China, Ireland as well as African nations.
London is home to a vast majority of these immigrant-run businesses with more than 188,000, compared to the next most popular location, Birmingham, which is home to nearly 20,000.
DueDil founder Damian Kimmelman said: "Immigration is one of Britain's most emotive topics for debate. Sadly, opinions are rarely informed by evidence.
"This game-changing research proves that migrant entrepreneurs are hyper-productive, net contributors to the UK economy.
"History tells us that the most productive states always encourage intellectual and technological ferment; that's what we're seeing in Britain right now, and we must celebrate it."
Matt Smith, director of the Centre for Entrepreneurs, said: "The contribution of migrant entrepreneurs is, to be frank, breath-taking.
"It is now the responsibility of politicians of all parties to celebrate migrant entrepreneurs' contributions and restate their commitment to maintaining pro-entrepreneurship immigration policies."BLOG COMMENTS POWERED BY DISQUS
