The politics of Belgium take place in the framework of a federal, representative democratic, constitutional monarchy. The King of the Belgians is the head of state, and the prime minister of Belgium is the head of government, in a multi-party system. Executive power is exercised by the government. Federal legislative power is vested in both the government and the two chambers of parliament, the Senate and the Chamber of Representatives. The federation is made up of (language-based) communities and (territorial) regions. Philippe is the seventh and current King of the Belgians, having ascended the throne on 21 July 2013.
Since around 1970, the significant Belgian national political parties have split into distinct representations for each communities' interests, besides defense of their ideologies. These parties belong to three main political families, though all close to the centre: the right-wing Liberals, the social conservative Christian Democrats and the Socialists forming the left-wing. Other important newer parties are the Green parties and, nowadays mainly in Flanders, the nationalist and far-right parties. Politics is influenced by lobby groups, such as trade unions and employers' organizations such as the Federation of Belgian Enterprises. Majority rule is often superseded by a de facto confederal decision-making process where the minority (the French-speakers) enjoy important protections through specialty majorities (2/3 overall and majority in each of the 2 main communities).
Constitution of Belgium and State reform in Belgium
The Constitution of Belgium, the primary source of law and the basis of the political system of the Country, was established on February 7, 1831. It has been changed several times, but the most relevant reforms were performed in 1970 and in 1993.
In 1970, in response to a growing civil conflict between the Dutch-speaking and French-speaking communities in Brussels, the Government declared that "the unitary state, its structure and functioning as laid down by law, had become obsolete".
