Today I finally received one, I’m worthy enough to be targeted by a bot.

I don’t know in naturalization cases, but in Spain members of the parliament who are from independentist parties (which basically want to go against the constitution and obviously don’t give a shit about the King) preceed their oath with the phrase “by legal imperative”.

Every time it happens some parties claim that it’s not valid but AFAIK there has been no ruling in favor/against it.

Members of the government make their pledge at the palace in front of the king and I have no memory of anybody using that phrase, I quickly looked for pledges made by republican politicians and they pledge loyalty to the king as well.
