Some nice pictures (especially the last one), taken on a dinner with politicians ('farewell' dinner, can't come up with a better translation :)):
‘Altijd veel over staatshervorming gesproken’ - De Standaard
Here an article about the reformation of dotations. It states the new dotations the members of the royal family will receive. This was decided before the abdication, so changes will be made ones Filip is king, I guess.
Hervorming dotaties: wie verdient wat? - De Standaard
The first amount is the total dotation, I think. The last one is the amount of taxes that would need to be payed. (it's the first time our royals have to pay taxes)
So, princess Xenia, you're quite right about the amount of Laurent and Astrid. It's not even 450000 euro and I assume it will be lowered in the future because of their new statuses.
Belgians like to complain, I guess :)
