President Recep Tayyip Erdogan is seeking to replace the parliamentary system with an executive presidency.
Approval could see him stay in office until 2029.
Supporters say a “yes” vote would streamline and modernise the country; opponents fear the move would lead to increasingly authoritarian rule.
The referendum could bring about the biggest change to the governing system since the modern republic was founded almost a century ago.
It also takes place under a state of emergency which was imposed following a failed coup last July. A government crackdown since then has seen tens of thousands of people arrested.
What’s in the new constitution?
- The president would be able to directly appoint top public officials, including ministers
- He would also be able to assign one or several vice-presidents
- The job of prime minister, currently held by Binali Yildirim, would be scrapped
- The president would have power to intervene in the judiciary, which Mr Erdogan has accused of being influenced by Fethullah Gulen, the Pennsylvania-based preacher he blames for the July 2016 coup against him
- The president would decide whether or not impose a state of emergency
Critics fear the change would put too much power in the president’s grasp, amounting to one-man rule, without the checks and balances of other presidential systems.
Sounds like Erdogan is seeking a mandate for a virtual dictatorship.
If he loses the vote is that going to stop him?
