Abstract
The first months of political life in Belgium in 1979 were essentially characterized by the great difficulties encoutered in the formation of a new cabinet. In 1979 Belgium lived its longest cabinet crisis in its history.As usual, the process of cabinet formation started with the nomination of an «informateur», followed by that of a «formateur». However, formateur Wilfried Martens did not succeed in forming a cabinet : oppositions on issues and strategies between the parties proved to a high to be surmounted. The King there upon introduced an innovation: he designated two «mediators». These, however, also failed to find some ground for agreement. Eventually, after elaborate informal contacts, the resigning Prime-Minister, Paul Vanden Boeynants, was nominated as formateur. After a month of laborious negotiations he successfully completed his mission. However, he preferred to leave the post of Prime-Minister of the new five party cabinet to Mr. Martens, till then president of the FlemishChristian-Democrats.
