Belgium is a parliamentary democracy with a proportional representation system and two linguistic groups, Flemish and French-speaking. There are currently 11 parties sitting in the lower chamber of parliament (Pilet 2021), along with two independent MPs. This is testimony to Belgium’s fair and accessible electoral system, despite a 5% electoral threshold since early 2000 (Reuchamps et al. 2014). Legal restrictions, such as requiring a certain number of signatures before an individual may run, are fair and are effective in controlling the number of candidates running for election. The same holds for parties, which can be relatively easily registered, possibly in a single district (or electoral “arrondissement”). In practice, of course, such restrictions may represent a higher de facto hurdle for smaller or local parties or candidates. Like in any country, established parties developed enhanced knowledge of registration procedures and of the law’s subtleties.
