The 2017 Turkish constitutional referendum 'Yes' campaign refers to a campaign headed by numerous political parties, non-governmental organisations, individuals and media outlets in favour of a 'Yes' vote in the 2017 Turkish constitutional referendum. If successful, the 'Yes' campaign will transform Turkey from a parliamentary republic into an executive presidency. The 'Yes' campaign is rivalled primarily by parties and organisations that lead a 'No' campaign'. Neither campaign has a united or centralised campaign structure, with rallies and campaign events being largely organised by political parties independently of each other.
