parliamentary democracy can mean A LOT of elections sometimes
people need a sense of stability while so many changes take place &
enemies should not think the country is in a weak state while the country changes prime ministers, parties & governments, so
the monarch has the power to make a government in his name
meaning after elections decide who has won the monarch gives the final stamp of approval but
the monarch cannot make laws nor make policy
the monarch just ensures the SYSTEM itself is safe and in place
he can have a branch of the military under him
to protect the existence of the SYSTEM itself
sometimes the monarch can be a tie breaking vote
