This article reviews the content of the proposed constitutional amendments, analyses the campaign including the strategies employed by the main political actors in the ‘Yes’ and ‘No’ camps and the resource advantages enjoyed by the ruling party, assesses the electoral performance of both sides through a summary of results from provincial areas and geographical regions, and considers how Turkish politics are likely to take shape under the new system. © 2017 Informa UK Limited, trading as Taylor & Francis Group.EnglishAKPCHPCompetitive authoritarianismConstitutional reformErdoganExecutive presidencyTurkeyAuthoritarianismConstitutional reformElectionElectoral geographyLeadershipParliamentParty politicsReferendumVoting behaviorChandipura virusReview10.1080/13608746.2017.1384341
