2007–2011 Belgian political crisis

The 2007–2011 Belgian political crisis was a period of tense communal relations and political instability in Belgium, which was rooted in the differing opinions on state reform, and in the continued existence of the controversial electoral district of Brussels-Halle-Vilvoorde (BHV). Parties from the Dutch-speaking Flemish Community are in general strongly in favour for a devolution of powers to the communities and regions, and the splitting of the unconstitutional BHV district, while French-speaking French Community of Belgium is generally in favour of retaining the status quo.
