Several reforms were brought into force in Belgium in the last twenty years. First of all, Belgium has become a federal state with its typical characteristics of assymetry and complexity: it consists of three regions and three communities which do not coincide completely. The federalisation process has led to linguistic agreements between the Flemish and the French community taking largely into account the specific situation of Brussels. Also budgettary agreements concerning the financing of the communities and the regions are a product ofthe federalisation process. In these decades Belgian government has also significantly taken care of its public finances: The deficit has decreased and Belgium now finds itself in the European average but it has given Belgium governments a hard time. Today Belgium has reached the objectives necessary to participate at the european monetary union. Fundamental changes in society have put ethical questions on the political agenda. This has led to arrangements in one way or another on subjects like abortion and made discussions on euthanasie and the use of soft drugs at least possible. Last but not least new rules were adopted concerning democracy and the functioning of political parties. Especially the way political parties will befinanced has been take care of but also measures increasing equality between men and women and procedures for more direct democracy. The reform of the judiciary has been tackled. These changes put forward that the role of the party leaders altered considerably. At the interface of political convictions and the management ot the state, the position is loaded multifunctionally due to the several levels of policymaking and the various ways of political expression.
