The Executive Divided Against Itself: Cohabitation in France, 1986–1988

From March 1986 to May 1988 France was headed by a leftist President and a rightist Prime Minister. The background to this unusual situation is presented, and the experience itself — referred to as cohabitation — is discussed in detail.
The complex game that the two executive leaders played during the period was regulated by the constitutional rules, conditioned by the electoral calendar and the narrowness of the prime minister's coalition majority, and moderated by public approval and the existence of a bipartisan foreign and defense policy.
The 1986–1988 experience did not overtax the constitutional system, but cohabitation under different conditions could be destabilizing. Cohabitation is like the possibility of the US president being selected by the House of Representatives: not highly probable but possible, not necessarily dangerous but possibly so, and something that arouses little enthusiasm.
