Half a million migrants who have arrived in Germany in the last 18 months have failed to register with authorities ‘and are either working illegally or engaged in criminality’

Half a million refugees who poured into Germany in the past 18 months have failed to register with authorities.

Officials say this means they are either working on the black market or have plunged into the criminal underworld to get money because no registration means no benefits.

Either way, officials are deeply worried about the numbers and are expected to discuss the issue at a cabinet meeting with Chancellor Angela Merkel tomorrow.
