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.
