Getting silly now.Because periodically the authorities would inspect suspicious businesses and if it is found that employees are working illegally (no I.D. card or fake I.D. card) the business is shut down.
Easy-peasy.
It is a clear pull-factor motivating the cross-channel boats and it should be addressed. All this 'invasion of privacy' stuff is just a smoke-screen. It saddens me that even Nigel Farage is opposed to I.D. cards, he should just shut up about the dinghy issue whilst he remains wedded to that belief.
Perhaps we could employ asylum seekers to raid businesses, looking for asylum seekers. After all, we wouldn't have people in hotels if we had enough people handling asylum applications.
