I would add to the list:
Controlling the BBC
Using the media as a propaganda tool
Refusing to appear on any program where they might be challenged
Brazenly not resigning when caught out in criminal or dishonorable acts
Changing electoral boundaries to benefit themselves
Bringing in legislation to insist on photo documentation to be on the electoral register (a trick learnt from the Republicans to make it hard for poor or black voters to register)
It all adds up to a usurping of democracy to me. They want a one-party state!
