18 months to form a government. Better luck next time, IraqBRUSSELS—Belgium's new cabinet will be sworn in by King Albert II on Tuesday, the royal palace said, ending a world-record 541 days without a federal government for the heavily indebted euro-zone country.
Elio Di Rupo will become the divided nation's first Francophone premier in 32 years, taking office in a Europe dominated by center-right governments in time for a European summit at the end of this week.
The palace said Mr. Di Rupo, who led the negotiations that broke the stalemate, presented the king with the names of ministers, who will be sworn in on Tuesday.
There are six parties in the ruling coalition, the result of 18 months of tense negotiations and a major state overhaul, and there must also be a vote of confidence in parliament in coming days so that Mr. Di Rupo can attend the European Union summit meeting here on Thursday and Friday.
Steven Vanackere, a Flemish Christian Democrat, will become finance minister, swapping jobs with Didier Reynders, who has been in the role since 1999. He must tackle euro-member Belgium's high level of state debt—just below 100% of gross domestic product—and restore confidence after a downgrade of its sovereign debt by Standard and Poor's 10 days ago.
A French-speaking centrist liberal, Mr. Reynders takes over as foreign and EU affairs minister. Melchior Wathelet becomes secretary of state with responsibility for energy, including the contentious "rente nucleaire," a levy paid by GDF-Suez SA for keeping Belgium's nuclear reactors open.
Mr. Di Rupo has said the government will draw up a policy on the closure of Belgium's nuclear reactors within six months of taking power.
"My first words are for the citizens," Mr. Di Rupo said last week, as he set out the new government's plans, including public-sector cuts and new taxes. "I want to thank them for their patience.…Together, we need to roll up our sleeves and get this country out of crisis."
Mr. Di Rupo, 60 years old, is head of the French-speaking Socialist Party of Belgium and mayor of the southern city of Mons.
He mediated an agreement among six parties for a coalition government and major state overhauls as Europe's debt crisis appeared to be drawing in Belgium, resolving a deadlock that had lasted since elections in June 2010.
The former chemistry professor, who is known for wearing a red bow tie, rose to power from a very poor immigrant background, with his appointment described as "the American dream, in Belgium.…He's someone who had to work very hard," by Vincent van Quickenborne, a political opponent from the Flemish liberal party, in newspaper Le Soir.
Born in 1951 in Morlanwelz in the southern region of Wallonia, Mr. Di Rupo was one of seven children in a family of Italian immigrants.
After his father was killed in an accident, his illiterate mother was forced to place some of the children in an orphanage, he said in a 2008 interview with journalist Francis de Woestyn in 2008.
The new prime minister faces numerous challenges. He has to trim public spending in line with European Union targets to get a balanced budget by 2015, without alienating his party's core support from trade unions.
He takes power as part of a diverse coalition that doesn't include the N-VA Flemish nationalist party, which won the most votes in richer, more populous Flanders.
Mr. Di Rupo, the first French-speaking premier since 1979, is often mocked for his shaky command of Dutch.
When he heads to the EU summit, he will be one of the few left-wingers at the table in a Europe where center-right governments, led by neighboring France and Germany, are steering the Continent's course.
He is also the first openly gay EU leader, having announced his orientation in 1997 when questioned by journalists.
Belgium has undergone one of its deepest political crises since World War II, with politicians from every language group and political party heading talks before Mr. Di Rupo found consensus on the wide-ranging state overhauls that led to a breakthrough in negotiations.
He will be working under time pressure: The country's voters return to the polls in just two years.
Yeah, that’ll end well when this government represents the majority of the minority.The country's voters return to the polls in just two years.
I’d be surprised if this government survives as long as it took to make.
