Prince Laurent even is known to have joke that he speaks ABN. That usually means the Dutch version of Queen's English but he decided that in his case it stood for Alles Behalve Nederlands (=All But Dutch/Flemish).
Elisabeth also speaks German but im not sure she is fluent in it. As the German speaking part of the Kingdom is only a minority it's enough for her to speak it next to English as a foreign language but she needs to be bilingual when it comes to French and Dutch. Fortunately she is.
Thanks Eric.
Is the Princess and her siblings 100% fluent in Dutch, French and German? How about the two previous genereations of the Royal Family?
