IMHO abdicating while retaining the title of King and Queen is a recipie for disaster. They abdicate the hard yards and yank the rug out from under the actual monarch, their own son. Who does that?
This sort of behavior does them no favours and certainly cements the poor opinion many people gained of them and the the way they treat their children which arose during the hospitalisation of Prince Laurent.
All in all it leaves one wondering exactly what they are about. It can't be their country - their behavior is sending confusing messages about who is the real King and who holds the real power and, it certainly isn't their children since it is their son King Phillipe who is left looking stupid.
In the photos of them voting they look such a sweet and benign couple. Whoever would imagine the machiavellian machinations of those two?
Perhaps there might have to be some further legislation regarding those who abdicate . . .
