Turkey rivals make last push before tense poll

Turkey's top politicians made a final effort on Saturday to sway undecided voters in a frenetic end to campaigning a day ahead of the closely-contested referendum on expanding President Recep Tayyip Erdogan's powers.

With election rules banning all campaigning after 1500 GMT, both the 'Yes' and 'No' camps squeezed in a flurry of rallies as the clock ticked down to Sunday's landmark poll.

Analysts see the poll as a historic choice on the direction of the NATO member which will shape its future political system and determine relations with the West.

If passed, the new presidential system will implement the most radical political shake-up in Turkey's recent history, dispensing with the office of the prime minister and centralising the entire executive bureaucracy under the presidency.

"Turkey will tomorrow make one of the most important decisions in its history," said Erdogan as he wrapped up an exhausting nationwide campaign with a rally in the Istanbul district of Sariyer.

Confidently predicting victory, he declared: "The polls look really good." But he urged people not to succumb to "lethargy" in voting, saying "the stronger result the better".

"A 'Yes' that emerges from the ballot box with the highest margin will be a lesson to the West," added the president, who has frequently railed against the European Union in the campaign.

'Last messages' 

Erdogan, who has dominated the airwaves in recent weeks with multiple daily rallies and interviews, gave no less than four rallies in Istanbul districts.

The standard-bearer of the 'No' camp, Republican People's Party (CHP) leader Kemal Kilicdaroglu, warned at a meeting in the Ankara region that Turkey was deciding if "we want to continue with the democratic parliamentary system or one-man rule".

He described the new system as "a bus with no brakes and whose destination is unknown."

The opposition has cried foul that the referendum has been conducted on unfair terms, with 'Yes' posters ubiquitous on the streets and opposition voices squeezed from the media.

The two co-leaders of the second opposition party the pro-Kurdish Peoples' Democratic Party (HDP), Figen Yuksekdag and Selahattin Demirtas, have been jailed on charges of backing Kurdish militants in what supporters say was a deliberate move to eliminate them from the campaign.

The poll is also taking place under a state of emergency that has seen 47,000 arrested in an unprecedented crackdown after the July 15 failed coup.

Despite the clear advantages enjoyed by the 'Yes' campaign, opinion polls have predicted drastically different outcomes and analysts are expecting a close result.
