According to Egelion's Constitution http://classic.particracy.net/viewconstitution.php?nationid=34, a 2/3 mayority of the Cortes Generales (the Parliament) can amend the Constitution. I have the required mayority and I need to do it since the country is currently a Kingdom but my electoral promise was to make it a Republic. The problem is that I can't find any option in the game to amend the Constitution.
I also want to propose a cabinet, but the following message appears when I try to do it:
"This nation does not have a head of state yet.
You do not have the right to propose a cabinet for your nation. Consult your constitution."
Please, I'm very new to the game and it's my first government. Help me and I'll let you use my natural resources
