Turkey is divided between those who are celebrating a win in a national referendum, and those demanding a recount.
President Recep Tayyip Erdogan has claimed victory in the vote, which looks set to grant him sweeping new powers.
This is what the major political figures are saying about the initial results on Sunday evening.
Turkish President Tayyip Erdogan has claimed victory during a speech in Istanbul.
“We are carrying out the most important reform in our history,” he said.
He also said voters abroad were a big part of the success.
The prime minister
Prime Minster Binali Yildirim, who led the Yes campaign alongside Mr Erdogan, said: “In our democracy’s history, a new page has opened.”
He addressed supporters from the balcony at the Justice and Development Party (AKP) headquarters in Ankara.
The main opposition, the Republican People’s Party (CHP), has called for a recount.
Deputy leader Bulent Tezcan denounced “violations” in the electoral process.
The pro-Kurdish Peoples’ Democratic Party (HDP), which has had two of its leaders imprisoned under President Erdogan, said the result would not be legitimate until an appeal was finalised.
“Our co-chairs being jailed, the referendum being held under a state of emergency, and other oppressive measures cast a shadow and legitimacy problem over the vote,” HDP spokesman Osman Baydemir told reporters.
The far right
The Nationalist Movement Party (MHP) opposition party had internal fights over the referendum and expelled a rebel member, Meral Aksener, who became a leading “No” campaigner.
Leader Devlet Bahceli, who led the party’s push for “Yes”, said the result was an “undeniably successful achievement” and should be respected, according to Reuters news agency.
Ms Aksener is disputing the result.
Germany got into a diplomatic spat with Turkey just before the referendum, when it refused to let President Erdogan lead political rallies on German soil.
About 1.4m Turks living in Germany were eligible to vote.
Just ahead of the final results, German Foreign Minister Sigmar Gabriel said, “We’d be well advised to keep calm and to proceed in a level-headed way.”
