ELI5: Why don't politicians get charged with libel when many of them knowingly lie or misrepresent facts?

Any lawyers out there? It seems like there should be laws for this but "I'm not a [lawyer]"

For a start, lying isn't necessarily libellous. You can say all sorts of untruths without defaming anyone.

Second...if you sued a politician for lying, just thing of the exposure you'd be giving their arguments? Money couldn't buy that sort of airtime (well, OK, in the US it probably can).

Third - some countries like the UK specifically exclude party manifestos from breach-of-promise rules. IIRC in the UK this came as a result of someone doing what you suggested.

So - apart from not working, being counterproductive and they'd just move the goalposts anyway, no reason at all!
