About this election
What was on the ballot
The referendum bundled 18 constitutional amendments into a single yes-or-no question. They abolished the post of prime minister and transferred executive authority to the president, who would head the government, appoint ministers and vice-presidents, issue decrees, and play a role in judicial appointments; raised the number of MPs from 550 to 600; aligned presidential and parliamentary terms at five years, to be held on the same day; and lowered the age of eligibility to stand for parliament. The changes would take full effect after the 2018 elections.
