Prime Minister Recep Tayyip Erdogan has won a sweeping victory in Turkey's presidential election.
He told cheering supporters at his Justice and Development Party's Ankara headquarters: "Without a doubt, new Turkey, great Turkey, leading Turkey has won today. We are closing the doors on one era, and we are now taking our first step to a new phase."
After 12 years as prime minister, Erdogan will now move into the presidential palace, which once belonged to the country's founder Mustafa Kema Ataturk.
His supporters say that the election has given him a mandate to take a more active role in politics than previous presidents, who were chosen by parliament.
But if Erdogan has proven his popularity, he is also a polarising figure and the opposition fear his presidency will see a rise in authoritarianism with fewer checks and balances on the power of the state.
On Inside Story, we discuss the challenges that lie ahead.
