the French-speaking electoral college, the party is represented in the Federal Parliament. Other minor communist parties are the Trotskyist Socialistische Arbeiderspartij (SAP) and the Linkse Socialistische Partij (LSP). Linguistic parties A specific phenomenon was the emergence of one-issue parties whose only reason for existence was the defense of the cultural, political, and economic interests of one of the linguistic groups or regions of Belgian society. See Flemish movement. The most militant Flemish regional party in Parliament in the 1950s and 1960s, the Volksunie (People's Union), once drew nearly one-quarter of Belgium's Dutch-speaking electorate. It was in the forefront of a successful campaign by the country's Flemish population for cultural and political parity with the nation's long dominant French-speaking population. However, in recent elections the party has suffered severe setbacks. In October 2001 the party disintegrated. The left-liberal wing founded Spirit, later called the Social Liberal Party, while the more traditional Flemish nationalist wing continued under the banner Nieuw-Vlaamse Alliantie (N-VA). After a disappointing result in the regional elections of 2009, the Social Liberal Party decided to fuse with the Flemish ecologists of Groen! The Vlaams Blok was another party created out of the Volksunie in 1978. In 2004 it disbanded and reformed as Vlaams Belang after a conviction for violating the Anti-Racism Law. It strongly advocated Flemish independence and the cultural assimilation of migrants. (see Nationalists/Conservatives below) Ecologists/Greens The Flemish ecologist party Agalev (Anders GAan LEVen - To Start Living Differently) made its parliamentary breakthrough in 1981. As a traditional green party, the three core values of Agalev were ecology, peace and participatory democracy. Following significant gains made in the 1999 general elections, the green parties of both regions joined a federal coalition cabinet for the first time in their history, but were ousted after the next elections. Agalev subsequently changed its name to Groen! (Green!). Nationalists/Conservatives Another nationalist party is the rightwing nationalist Vlaams Belang (Flemish Interest), the successor of the Vlaams Blok (Flemish Block) which broke away from the Volksunie in 1976. Originally a mainly Flemish regionalist and republican party, the Vlaams Blok soon concentrated on anti-immigration themes, and was often accused of xenophobia and racism. Its viewpoints on ethical and moral issues is very conservative. Party chairperson was MEP Frank Vanhecke, but Filip Dewinter is considered by many to have been the party's real leader. Long dismissed as a "fringe" party by mainstream politicians, the Flemish Block
