Actually, they dont got any power in sweden, they're more for show than anything else and also they act like diplomats if it comes governmental leaders from other countries comes to sweden,
we got election every 4 years for a new government, then that government chooses a person who will represent sweden and order people around,he's generally from that political group but every desicion needs to be approved by the government... so he can't take over sweden and turn it to a dictator ship, even thought sweden is the most democratically country doesnt mean people are any happier
oh, good night ^^
