Turkish President Recep Tayyip Erdogan has approved a controversial bill that could see him stay in office until 2029 before it goes to a country-wide referendum. Opponents of the bill have stated that the changes would remove some checks and balance of the president that could lead to Turkey being under a "one-man rule". "The YSK will probably announce that April 16 is the appropriate date for a referendum", Deputy Prime Minister Numan Kurtulmus told reporters.
Erdogan says the reforms will provide stability and prevent a return to fragile parliamentary coalitions of the past.
Simultaneous parliamentary and presidential elections for a five-year term in Turkey would be held in November 2019.
Turkey's parliament approved the reform package in contentious and sometimes violently debated sessions last month.
Under the new constitution, the president will have strengthened executive powers to directly appoint top public officials including ministers.
The reform would also allow Mr Erdogan to become leader of the ruling party while in office again, and possibly stay in office for another 12 years. The president-elect will not be obliged to be a non-party nominee any more.
The referendum campaign is due to formally kick off on Feb 25, with Mr Kurtulmus expressing hope it would reflect "the maturity of Turkish democracy".
The move has been criticized by opposition parties as an attempt by the president to grab power, but Prime Minister Binali Yildirim argued the vote would ultimately put more power into the hands of the people who would pick the government and the president.
President Erdogan has steadily consolidated his control of Turkey's branches of government since his election in 2014.
