Find it quite ridiculous that people seem to believe he'd want to be in Britain "for the benefits". To claim benefits he would have to legitimise his status in the country by officially seeking asylum to get "on the books" - it seems highly unlikely that someone who would risk themselves clinging to the bottom of a lorry is then going to risk declaring themselves as asylum seeking when they get here when it might well mean being sent straight back out of the country on the next flight.

No. He would not have been here to sit claiming benefits. More likely, he would be working for an unscrupulous employer for slave wages (usually £3 or so an hour).

With that in mind - the problem with the UK that is attracting ILLEGAL immigrants (to reiterate, illegal immigrants cannot claim benefits without revealing themselves!) is the fact that there are people employing them illegally for low wages. It's these employers (exploiters) who need to be cracked down on to stop Britain from being attractive to illegals. Not the benefits system.
