Deporting a backlog of foreign criminals will take decades at current rates for certain nationalities, a devastating new analysis shows.

A wide range of convicted criminals – particularly those from African, Middle Eastern and Caribbean nations – are being removed from Britain at a glacial pace.

Shadow Home Secretary Chris Philp, who compiled the analysis of government data, said it was ‘totally unacceptable’ that some nationalities are not being deported.

There are 145 Eritrean criminals in jail here, according to latest data, but in the 12 months to June only two were removed.

It means the Government will take 73 years to deport the total number at current rates, according to the new research.
