There is supposedly a network of local and national govt computers that are used for cross checking benefit claims for fraudsters ie have they given the same info about their offspring to local council (housing benefit) dhss (income support) hmrc (tax credits) a lot of these morons claiming benefit for 8 ficticious kids get the names and dates mixed up etc. I'm putting this into the context of illegals who are on false papers/have stolen an identity. For overstayers all they need do is keep a close watch on petrol stations, ethnic restaurants, car washes, doctors surgeries, Western Union outlets and so forth
