Immigrants who don’t understand English have been able to buy language certificates that give them the right to settle in Britain.

An investigation by The Sunday Times has found that staff at English language colleges in London and Birmingham have been offering migrants who speak little or no English Home Office-regulated English and Citizenship certificates for £250 each. Tests are rigged to allow almost anyone to pass.

Staff hand out crib sheets with questions and answers in English. Others let candidates write the sound of English words on the sheets in their own tongue, so the answers appear right, but they don’t know what they are saying.

At the UK Learning Academy in Birmingham, a staff assessor told an undercover reporter that candidates did not have to take any courses or speak any English to pass the tests. The assessor simply asked if the candidate knew their own name, date of birth and address. When told that they did, the assessor replied: “That’s all right then. That’s a guaranteed pass.”

Yesterday the Academy said it had sacked the assessor for “gross misconduct”. Directors at a second college under investigation said they had suspended its English course, while a third college removed the website advertising its course.

Chris Grayling, shadow home secretary, said: “These revelations are particularly alarming and reveal another major abuse of our system for immigration.” He called for the certificates to be suspended.
