Parliament’s approval paved the way for a nationwide referendum on the amendments, which will give the president, a traditionally more ceremonial role, the power to dismiss ministers and Parliament, issue decrees, declare emergency rule and appoint figures to key positions, including the judiciary.
It will also allow the president to be a member of a political party, which is currently prohibited under the constitution as the presidency is expected to exercise impartiality.
The reform will enable Erdoğan to take back the leadership of the ruling party and govern until 2029.
The plans foresee presidential and general elections in 2019, with a maximum of two five-year terms.
