Back in the day the Tories were dead against this kind of "Big-Brother" snooping. I mean, the bank checking is just the tip of the iceberg when it comes to what powers the government actually want to give to the DWP: They want to give them police powers like arrest and seizure of assets, and the ability to demand detailed information from anybody who is connected with someone under investigation, whether they themselves are claiming benefits or not. It will be a field day for anyone who likes making malicious reports to the Jobcentre.
