The UK doesn't elect governments, we elect parliamentary members and they suggest an FM or PM to the King who then suggests a cabinet to the King.
And back in the real world, of course we elect govts. How many times have you read on here that people don't like or don't know their MP but vote gir them vecayse they're Labour etc. Or they won't vote for their Labour MP because of teans ussues, regardless of what their individual MP says. I'm sure there are some people,who vote fir their MP because they like them personally, but the overwhelming majority of people vote fir a party to govern.
This isn't something the SNP have proposed as a policy which has been voted on via a manifesto
The Scottish govt have changed the rules. They can change the rules re letting the public know what the monarch's response was too if they wanted. This is down to the govt, not the monarch.
The King’s involvement, under rules known in Scotland as crown consent, can be revealed after the rules at Holyrood were changed. Holyrood’s presiding officer, Alison Johnstone, told the Scottish government it now had to inform parliament as soon as a new bill was tabled whether the monarch had been allowed to see it first. What the government does not say is whether any changes were made to the draft bill at the King’s request and, if so, what those were.
