Recep Tayyip Erdogan is due to be sworn in as Turkey’s First Executive President with vastly expanded powers on Monday, when he also plans to announce his cabinet.
Erdogan is scheduled to take the oath of office at the Grand National Assembly in Ankara at 4:30 pm (1330 GMT), as Turkey completes its transition from a parliamentary model to an all-powerful presidency.
The radical changes were approved by a razor-thin majority in an April 2017 constitutional referendum.
Erdogan would become both the head of state and government, with the prime minister’s post abolished.
He will have sweeping new powers, including over the judiciary and the ability to rule by decree.
He won re-election on June 24, with 52.59 per cent of votes.
In parliamentary polls held the same day, his ruling Justice and Development Party (AKP) secured a majority through its alliance with the far-right Nationalist Movement Party (MHP).
After taking the oath, Erdogan plans to visit the mausoleum of Mustafa Kemal Ataturk, the founder of the modern, secular ,Turkish Republic.
His inauguration at the 1,150-room presidential palace will be attended by 22 presidents and 28 prime ministers and parliament speakers, among others, state News Agency, Anadolu, reported.
Erdogan has been in power for 15 years, first as prime minister, and then as president, from 2014.
Under the new system, the counting of terms starts afresh, which means he starts his first five-year term on Monday.
There is a two-term limit on the office of the president, so he could effectively stay in power until 2028.
