 De Gaulle's opposition to supranationalism and fear of the other members challenging the CAP led to an "empty chair policy" whereby French representatives were withdrawn from the European institutions until the French veto was reinstated.Eventually, a compromise was reached with the Luxembourg compromise on 29 January 1966 whereby a gentlemen's agreement permitted members to use a veto on areas of national interest.On 24 September 1963 the members reached an agreement on merging the executive bodies of the three Communities.
