The seventeenth session of the Council of the International Civil Aviation Organization opened in Montreal on September 9, 1952 and concluded on December 5. The Council sanctioned the holding of a special frequency meeting to consider certain problems associated with frequency assignments in the European-Mediterranean region in Paris in October and decided that the first ICAO Air Navigation Conference should be convened in Montreal in February 1953. After discussion and exchange of views, the draft agenda for the 1953 ICAO Assembly was referred to the Air Navigation Commission, the Air Trans-port Committee, the Finance Committee, and the Committee on Joint Support of Air Navigation Services for their consideration and report. After withdrawal by the French government of its invitation to hold the seventh session of the Assembly in France, the Council accepted the invitation of the United Kingdom and decided to hold the seventh session in Brighton, England, opening on June 16, 1953.
