I think the UK has an extraordinarily bad track record of allowing freedom of expression. Regarding ofcom though, they actually perform very little regulation of accuracy and impartiality, most of their work is as an ordinary utilities regulator, much like the FCC. To describe their regulatory action of section 5 of their broadcasting code (the part related to accuracy and fairness) as “working fairly well” is generous. I’d say a better description would be “not really functional”.
