It does look like either the Labour or the Tories favour surveillance heavily. It makes me wonder, do the leaders of these parties actually believe that such surveillance can ensure security ? Or, is it that most of the common people see surveillance as a good security measure and the political parties are just appeasing these people. I can't help but extrapolate this situation to the scenario depicted in "V for Vendetta".
There is also the opposite problem. The public aren't asking for it not to be done either. Internet surveillance isn't a hot button political topic either way. However, terrorism is. Hence the problem.
