This was actually put into practice during the Spanish transition to democracy. The King gave a televised address denouncing an attempted fascist coup and ordered them to stand down: https://en.wikipedia.org/wiki/1981_Spanish_coup_attempt#Juan_Carlos's_repudiation https://en.wikipedia.org/wiki/1981_Spanish_coup_attempt#Juan...

I can't find it anymore, but there was a good drama movie about these events on Netflix a while ago.
