""Vive le Québec libre!""
 (] , "Long live free Quebec!")
 was a controversial phrase in a speech delivered by President Charles de Gaulle of France on July 24, 1967, during an official visit to Canada under the pretext of attending Expo 67 in Montreal, Quebec.
 While giving an address to a large crowd from a balcony at Montreal City Hall, he uttered ""Vive Montréal; Vive le Québec!""
 ("Long live Montreal, Long live Quebec!")
 and then added, followed by loud applause, ""Vive le Québec "libre"!""
 ("Long live "free" Quebec!")
 with particular emphasis on the word 'libre'.
 The phrase, a slogan used by Quebecers who favoured Quebec sovereignty, and de Gaulle's use of it was seen by them as giving his support to the movement.
 The speech sparked a diplomatic incident with Canada's government, and was condemned by Prime Minister Lester B. Pearson, saying that "Canadians do not need to be liberated".
 In France, though many were sympathetic to the cause of Quebec nationalism, de Gaulle's speech was criticized as a breach of protocol.

The Fouchet Plan was a plan proposed by President Charles de Gaulle of France in 1961 as part of De Gaulle's grand design for Europe at the time.
 His plan included a three-power directorate, consisting of France, Britain and the United States.
 His plan also included the Fouchet Plan.
 It was written by Christian Fouchet, France's ambassador to Denmark.
 The idea was to form a new 'Union of States', an intergovernmental alternative to the European Communities.
 De Gaulle feared a loss of French national influence in the European Communities, which was becoming more and more supranational so the Plan was an attempt to keep the balance of power in France's favor.
 The success of the European Communities and the lack of enthusiasm of other states for the idea stopped the implementation of the Fouchet Plan.
