The king's Wednesday announcement that that he will step down on his country's national holiday, July 21, and hand the throne to his less popular son has fanned long-simmering debate in Belgium about reining in the few powers the king still wields.
"We now have momentum to adapt the monarchy to the 21st century," Jan Jambon of the nationalist New Flemish Alliance told Parliament during a special meeting to discuss the abdication. "Let's grab this chance with both hands."
The Belgian monarchy is already largely ceremonial, but plays a key role in nudging politicians to make compromises in post-election government formation talks.
Albert's reign has been marked by a growing rift between Belgium's French and Dutch-speaking camps. A Belgian breakup was averted in 2011—after a political stalemate lasting 353 days—with a reform deal giving each side far-reaching self-rule powers.
Jambon, whose party wants a Flemish, Dutch-speaking republic, called the king's powers "feudal legacies" that should be scrapped.
The monarchy gets a warmer welcome in Wallonia, Belgium's French-speaking south, than in Dutch-speaking Flanders, Belgium's more populous and economically more powerful north.
"The monarchy really has no place in modern democracies, but it enjoys broad support in Belgium. The question is: how can the monarchy fulfill its role in the new Belgium?," said Wouter Beke, leader of the Dutch-speaking Christian Democrats.
Prime Minister Elio di Rupo praised Albert's 20-year reign and said the new monarch would help Belgium further bounce back from the 2011 political crisis. "Now that we are getting a new king, we can face the future serenely, full of confidence and optimistically," he said.
Di Rupo sparked hilarity as he informed Parliament about his abdication discussions with King Albert. He said after those Tuesday talks, "I contacted Prince Philippe to inform him about the situation." The comment drew laughter because it sounded as if the crown prince was unaware of his father's abdication.
In his first public comment on the abdication, Prince Philippe paid tribute to his 79-year-old father's 20-year reign. The 53-year-old prince, who is seen by many in his nation of 10.5 million as awkward and reclusive, says he is conscious "of the responsibility that befalls me."
Philippe will become the second crown prince to ascend to a European throne this year, following in the footsteps of Willem-Alexander, who became king of the neighboring Netherlands on April 30 when his mother, Beatrix, abdicated.
