A protest was held in Westminster today to mark the fifth anniversary of the deportation of thousands of students from the UK.
Claims of cheating over an English Language test in 2014 led to the Home Office revoking the visas of tens of thousands of people, many given no right to appeal.
However, campaigners say cases that have since made it to the courts, have shown no evidence to back up the accusations and are now calling for an independent inquiry.
In response, a spokesperson for the Home Office has said:
The investigation in 2014 into the abuse of English language testing revealed systemic cheating which was indicative of significant organised fraud. The scale of this is shown by the fact that over 20 people who facilitated the fraud have received criminal convictions, with prison sentences totalling 68 years.
