Two of the major parties support it, but it's not entirely obvious how much public support there is; it's not most people's top issue, and it's easy to make polls say what you want depending on the question you ask.

You'd get different answers if, for instance, you ask "do you want to have to show ID or submit a picture of your face in order to access many sites on the Internet".

I'm not sure there'd be much of a difference because the British people are broadly speaking a rather paternalistic society.

The entire concept of public support breaks down when the majority of the public doesn't actually know what a VPN is.
