Future Dutch king Willem-Alexander has undergone a remarkable transformation from his image as a boozing Casanova, ill-equipped for the throne, to a serious family man well-loved by his people. Due to take over from his mother, Queen Beatrix, when she abdicates on Tuesday, he has been preparing for his accession by taking on more and more duties in a bid to shake off his immature reputation. In an interview two weeks before the ceremony, Willem-Alexander, who turned 46 on Saturday, said he wanted to be a traditional 21st-century king but would not be a "protocol fetishist".

The Netherlands' Willem-Alexander becomes Europe's youngest monarch Tuesday when Queen Beatrix abdicates and his country hails the avowedly 21st-century king with a massive orange-hued party. Willem-Alexander, 46 on Saturday, will be the first Dutch king since 1890 and the first of a new wave of European monarchs, whose ageing blue blood -- average age 71 -- is increasingly watered down.
