DELFT, NETHERLANDS - APRIL 24:  Dutch Queen Beatrix's second son, Prince Johan Friso and Mabel Wisse Smit arrive at the at the City Hall on April 24, 2004 in Delft, the Netherlands. The Dutch government, required by the constitution to approve royal marriages, refused to sanction this match because Wisse Smit had formerly had a relationship with the late gangster Klaas Bruinsma. The Prince thus gives up his claim to the throne, but does retain his royal title of Prince Of Oange-Nassau. (Photo by Michel Porro/Getty Images)
