This is a video in Dutch about the relationship between Princess Mabel and criminal Klaas Bruinsma.
From Dutch NOS TV:
Prince Friso and [his wife] Princess Mabel [of the Netherlands] have themselves changed the entry about Mabel at the English language version of the Internet encyclopedia Wikipedia. The government information service RVD has confirmed this item in daily NRC Handelsblad.
Through an internet link at palace Huis ten Bosch, where the queen lives, the couple changed the sentence which said that Mabel before her marriage gave “incomplete and false information” about her [sexual] relationship with the drugs criminal Klaas Bruinsma. The words “and false” were removed.
According to Wikiscanner, a web site which can find out from which computer a Wikipedia article was changed, the text was changed on 8 January 2006.
Wikiscanner, which has existed for just two weeks now, has already uncovered various examples of institutions and corporations which changed entries about themselves. In this way, eg, the CIA and the Vatican tried to whitewash their public images on Wikipedia.
That the controversial words by now have been restored by a visitor speaks for the self cleaning capabilities of the online encyclopedia. This visitor, in a comment, points out that “onvolledige en onjuiste informatie” ["incomplete and false information"] are a literal quote by [Dutch] Prime Minister Balkenende.
Also the Dutch Wikipedia says “according to Prime Minister Balkenende, onvolledige en onjuiste informatie”.
