At 13 June 1999, elections for the regional Parliaments, the federal Parliament (both House of Representatives and Senate) and the European Parliament were held in Belgium. The percentage of voters casting a preferential vote at these elections increased again, reaching the highest score ever in Belgian history. On average, 60,9 % of the electorate expressed their preference for one or more candidates. Although voters have the possibility to cast a multiple preferential vote (i.e. a vote for several candidates figuring on the same party list), this possibility is not used very much. A voter who cast a preferential vote, only vote on average for 1,73 candidates. The further increase in preferential votes was a little surprise since strong limitations were imposed upon campaign expenditures and on commercial affichage. Political and social evolutions, such as individualism, anti-party feelings and mediatisation seem to have had a stronger impact upon preferential voting than these material limitations. The use of the preferential vote varies from one constituency to another, from Flemings to Walloons, and from one party to another. There were some notable evolutions. The voters of the extreme-right Vlaams Blok and of the green parties Agalev and Ecolo, who traditionally cast less preferential votes than voters of other parties, have dimished the gap between them and the other parties. Another important evolution is the decrease of pref erential voting in some constituencies in Wallonia. As for the Senate and the European Parliament, more Flemings now cast a preferential vote than Walloons do. The large constituencies used for these elections seem to attract very well-known politicians and as a consequence also very much preferential votes in Flanders. Despite the increase in preferential voting, the order of the list, composed by the party remained in most cases decisive whether or nota candidate was elected.
