It is mind-boggling, but the US Constitution doesn't do that.

It's not unique in that.

Bad-faith pollution of truth is a new legal concept, and only a few countries have explicit legal protections against it.

The UK had a case a few years ago where this was tested, the judgement was "Well, if we expected our politicians to tell the truth, where would that end, nyuck nyuck nyuck?"

It's actually a tacit assumption that politicians and representatives lie, the media lie, and this is how things are.

There are proposals in the UK and Wales to change this. My guess is they won't get anywhere near explicit approval in the UK. They might in the Welsh Senedd.

Meanwhile the US has Fox claiming that it's an 'entertainment' channel, and no one should expect truth or honesty from it.
