"The Cold War created serious ideological divisions, and the growing intrusiveness of political parties, encouraged by the proportional electoral system and the lack of alternative governments, led to clientelism, corruption and inefficiency. Land parcelling, hidden financing and parliamentary consociationalism led to a regression of the parties, prompting the intervention of the judiciary. Almost all parties, subjected to serious ideological erosion, had to change their names, symbols and leadership as a difficult transition to a new majority political system began. (chap. 7, pp. 83-84)"
