So it’s actually the Military that’s in charge of Thailands government. Its a constitutio al Monarchy much like England but the ruling government has been the Military for around 10 years now. The Kings mostly a figurehead just like King Charles. The last King of Thailand was so popular that he could significantly influence the people if he chose, the current King is largely seen as a useless playboy.
Thailand does have a lese majeste law which makes it illegal to insult the King. They are not the only country with such a law, ex. Germany has a similar law making it illegal to criticize the president (though it seems to be largely unused) and Denmark has a law preventing the ridicule of its Monarchs.
So it’s the Military that’s trying to oust an upstart civilian governmental party/movement. They seem to be using the lese majesty laws as an excuse to oust their rivals. I’m not sure just how effective it’ll be since the current King isn’t very well liked. Then again I’m sure they’re running their propaganda beside pictures of the late King who was beloved. Someone with closer ties to Thailand may be able to tell us how receptive people seem to be to this move.
