UK has always been one of the big leaders in censorship. I doubt that'll change anytime soon.
As an aside - I feel it's unfair to compare countries like UK and US to China. There are no misconceptions in China about censorship - everyone knows it happens, everyone knows what their govt. is up to. In America and the other colonies, civilians will believe any lies the TV tells them, and just lap it up.
Truth be told, CN censorship is not much different at all from US/UK. You're just not fully aware of how deep it goes in your own country.
