Belgian Prime Minister Yves LetermeIs there anything more holding Belgium together than “the king, the football team and certain beers”–  as Belgian Prime Minister Yves Leterme once said?Dutch-speaking Flanders and French-speaking Wallonia have their own political parties and their own television stations and newspapers which on any normal day could be reporting on totally separate countries.Tuesday was not one of those such days. Following Leterme’s decision to quit on Monday night, Belgium’s media at least agreed on the top story, even if few could answer the question: what next? The days ahead are likely to lead to growing debate over a central Belgian question: is it worth staying together?Belgium has evolved since 1970 from a unitary state to a federation in five phases of devolution giving regional and linguistic parliaments control over education, culture,transport and housing.The Flemish majority want more, from powers to set their own job creation schemes and to vary rates of tax. French-speakers fear that Belgium will be nothing more than an empty shell and the economic divide between rich Flemish north and their depressed south will widen.Leterme’s Flemish Christian Democrats had promised change, but his failure to broker a deal led to his resignation. Opinion polls are notoriously volatile, but a recent poll of Flemings found that more than 49 percent would welcome the country splitting in two.Even many Flemish who want a united Belgium struggle to say why, often citing the enormous headache that division would cause — how would the national debt be split and what would happen to Brussels, the largely French-speaking capital withinFlanders?During the last political crisis, less than a year ago, the capital Brussels saw a burst of colour as patriotic Belgians hung the national flag from their windows and balconies.French-speakers are mindful of the economic impact of losing their richer northern neighbours, but they too are losing patience.The demands of the two communities could simply be incompatible and the question remains — is Belgium ungovernable and incapable of reform?
