Labour leader Ed Miliband has said the the government's handling of the immigration system is "turning into a shambles", following reports that language certificates that offer smooth entry in the UK are being sold illegally for £500.
"We want tough controls, we want the right controls to be in place," he said. "I think we need urgent answers on what has been going on here."
A director of the firm that allegedly offered to fraudelently sell language certificates to migrants has said the practice was confined to one branch, where tests have now been suspended..
"I'm shocked that this has happened and am very concerned as to how it could have happened," Learn Pass Succeed's Uzwan Ghani was quoted in the newspaper as saying.
"We are very thorough when it comes to checking IDs of candidates before they take the test, so I will have to investigate which of the centres the test was taken in and who the assessor was.
"I've been in the business for five years and I've never come across something like this and I would not allow it. It is wrong and ridiculous."
