I made no insult. If that was the government's opening of parliament speech, so be it. For some reason I couldn't open the article in the OP. The UK Parliament has The Queen's Speech, an expression of the plans of the government, read by the monarch. It is political, but does not represent any political opinions of the Queen. If that's the same as your king's speech, then I can see there's no interfering going on.
Occasionally, in the UK, Spain (and perhaps the NL?) members of royalty forget themselves and make political statements that they have no business making. Prince Charles and Prince Philip have been known to do this and are often put in their place by elected officials. That is what should happen. Royals should remain outside of politics, they really have no role to play in day-to-day government.
The fact that you took my very mild comments as insults, suggests you might be a little blinded by your love of royalty. That happens here in Spain too, when anything other than sycophancy is seen by some royalists as insults to the monarch, and the judiciary often seems happy to trample on free speech to 'protect the dignity' of the titular figurehead at the 'top' of society. If you see my comments as insults, too bad; you need to get some perspective.
Yes, he has not input in the message at all. In fact it is exactly the same as in the UK.
In the Netherlands the government is responsible for comments made by the king/queen. All things she say in theory have to be vetted by the government. The Dutch government is also responsible for all actions made by people from the royal house (the small circle of royals who are in direct and immediate line of succession).
The rest of the royals are much more free to do what they want etc.
There have been a few problems, most of them purely in the personal realm of the royal family. Our current king in the past has made some remarks that can be classified as "less smart" but the current generation of royals (and the one before) have rarely lead to problems or issues.
The grandfather of our king (prince Bernhard) has had some real problems. The husband of the queen at that time had accepted 1.1 million from Lockheed Martin to ensure their plane won from the French Mirage plane. A parliamentary investigation came to the conclusion that he had received that money but generally it was known that he did not personally profit from that money but people around him did.
He was forced to step down from several public functions (board member of several companies etc.) and was never allowed to wear his military uniform ever again. He was very sad about that one. He also cheated on the queen and sired other children.
But he also did a lot of good for the country, he fought the Germans (his own people as he was born German), was a good business man, saved the monarchy and was co-founder of the Bilderberg group and last but not least, he helped founding the world wildlife fund and was it's first president from the moment it was formed in 1962 until 1976.
He also was an enemy of the Nazi's. He, as a Dutch citizen and officer, cut off all his nazi supporting family members and when he negotiated with Germans for surrender in 1945 he refused to speak German and conducted the negotiations purely in Dutch.
He was a wing commander in the RAF (he was referred to as wing commander Gibbs). He bomber V1 launching pads, bombed Pisa, attacked german submarines and flew reconnaissance over enemy territory. In 1944 he became Commander of the Dutch armed forces. He was seen by many as a real war hero.
He saved the monarchy, when our queen had fallen into the hands of a faith healer. With the help of the government this faith healer was banished and the monarchy had been saved.
He was a colorful figure who had some problems but overall he was a good man.
I am a great supporter of the royal family so I took your unfounded accusations/generalizations as an insult, if I went over the top, then I apologize.
