DELFT, NETHERLANDS - APRIL 24:   Prince Johan Friso & Mabel Wisse Smit arrive at the church 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 Pascal Le Segretain/Getty Images)
