Which isn't surprising; considering that, ever since the end of the first World War, the British royal family did everything they could to get the people to love them. Thing is though, they don't actually have any power anymore (as Elisabeth II demonstrated by trying to exercise one of her supposed powers to help out Boris Johnson, only for her to be brushed aside like she didn't matter); Parliament are the ones actually in control of the government, not King Charles III.
A lot of soft power resides with the government, yeah. It has to in order for things to be kept running.
But here's the kicker: there's a hard stick the reigning monarch
could use.
All the armed forces (including the Navy now, which amusingly they didn't 'have to' until recently) and police swear an oath to the
Crown, not
Parliament.
Everyone. The reigning monarch can still veto anything that the government wants to do with the Armed Forces. Hell, they could order them into Parliament to arrest everyone there
in theory. Reality? Rubber stamp shit and not even bother to interfere.
But the oaths are still valid -- the loyalty is to the Crown, not the government. They run it on
behalf of the Crown.
Another big stick, and it'd never happen obviously, is that Charles could basically dissolve Parliament and the current
form of government with a snap of his fingers.
Unfortunately, and again it'd never happen, with how much of a clusterfuck things have gone, many people were asking for the Queen to Thanos Snap Parliament a few years back -- and, yes, people were and still
are that pissed at how ineffective and corrupt the Commons (and Lords) are.
But although it
would never happen, it still
could. A lot of the Republicans out there dislike this Sword of Damocles over Parliament's head. shrug
