I know my opinion is a minority one, but as far as I'm concerned we'd rid ourselves of the monarchy.
Has this ever been a serious option. No-one in the UK seems to be up for the debate and the republicans have appalling timing.
Rougly 15% of the Dutch prefers a republic over the monarchy. No political party of importance has the republic on its wishlist. Conservative parties strongly support the monarchy and more progressive and liberal parties fear loss of votes when they make a party issue from it. When we consider that the king has no political power and minimal influence, he doesn't get much opportunity to dent popular support (some 75%).
There are some non-party republican movements, but they do little more than talk about it among themselves. So in conclusion: I don't expect to live and see the third Dutch republic.
