Opponents have accused Erdogan of marching towards authoritarian rule, comparing the executive presidency to sultans of the Ottoman Empire. In Turkey's system, amendments to the constitution need to be approved by 367 of 550 members to become law.
In the referendum, the proposed changes will then be sent to a public vote, and if it receives the majority's support, will be implemented.

Erdogan assumed the presidency, a largely ceremonial position, in 2014 after over a decade as prime minister.
