Amsterdam: Prince Johan Friso of the Netherlands and his wife Princess Mabel edited information about her past in the encyclopaedia Wikipedia, the royal family said on Friday.
Friso, 38, the younger brother of heir to the throne Prince Willem-Alexander, gave up his place in the line of succession in 2004 when he married Mabel Wisse Smit without official consent because of a controversial relationship she had had with a Dutch drug baron.
A spokesman for the Dutch royal family, headed by Queen Beatrix, confirmed that the entry on Wikipedia describing Mabel's relationship with slain drug baron Klaas Bruinsma had been changed from a computer in one of the queen's palaces.
When Friso asked the Dutch parliament in 2003 for permission to marry Mabel, Dutch media published details of her relationship with Bruinsma, who was shot dead in 1991.
