Our wonderful Prime Minister is pushing a bill to make online digital ID compulsory for Britons. Apart from the sheer impossibility of making it work without crippling the internet, and the huge costs of making it work even it it were possible, especially with multiple countries involved with differing interests and competing schemes, it would massively invade everyone's privacy.
There's a petition against it here if anyone is interested...

Including most that purport to come from the government.
