Prince Johan Friso of the Netherlands will retain his royal title, despite giving up his right to the throne to marry without the government's approval.

Friso, second son of Queen Beatrix, will lose his claim to the Netherlands throne when he marries Mabel Wisse Smit on April 24.

The marriage was not sanctioned by the Dutch government because Wisse Smit once had a relationship with a known gangster, and the pair tried to conceal it.

But by a royal decision approved by the government Friday, the 35-year-old Friso will retain the title "Prince of Orange-Nassau" and any children will be dukes or duchesses.
