It's an ongoing process. Decade on decade new controls are introduced but almost never rescinded. Part of it is a desire to control, part of it is that virtually every regulation is there for good reason, though as with Part P a critical analysis may show that the cost/benefit case is totally unsustainable. The politician's fear is that if they remove a control one week and something related happens the next week the Daily Mail will tear them to pieces for doing so. I mean Jenny Tonge MP's daughter wouldn't have been electrocuted if we'd had Part P would she?
