I doesn't surprise me one bit. There will always be opportunist leeches who will take advantage of whatever is on offer.
Therein lies our REAL problem. After the war, the government put in place the 'welfare state' which, at the time, was a very beneficial move. Over the decades, however, the wrong sort of people have seen a means of living well for no effort and have learnt all the ins and outs of how to play the system. More recently, the message has spread to foreign parts and the result is swarms of locusts queuing up to come and join the party by any means they can find.
There is one patently obvious answer as far as I can see: stop the handouts. Anyone capable of working should be given jobs that need doing but no-one wants to do: cleaning the streets, washing away graffiti, maintaining the homes and gardens of the old and incapacitated. If they don't like it, tough. Find a job you like better or go without.
Needless to say, the other immediate action that should be taken is to leave the EU - we are being taken for mugs - and repatriate all illegal immigrants.
