Turkish politicians hold their final campaign rallies Saturday for a vote many fear is unlikely to bring an end to months of instability as the country confronts bloody Takfiri attacks and a renewed Kurdish conflict.

Opinion polls are predicting a replay Sunday of the shock June election which stripped the Justice and Development Party (AKP) of its majority after 13 years of single-party rule, leaving the country without a government after coalition talks failed.

Turkey goes into the election more polarized than ever on ethnic and sectarian lines, and deeply on edge after the October 10 bombings in Ankara that killed 102 people, the worst in the country's modern history.

The AKP of President Recep Tayyip Erdogan is tipped to win between 40 and 43 percent of the vote, paving the way either for a shaky coalition that many analysts say will not last long -- or yet another election.

"Sunday's vote will have existential importance on the future of Turkey," said Yusuf Kanli, a commentator at Hurriyet Daily News.

Another inconclusive result could trigger further turmoil in the Muslim-majority country, with fears of a return to all-out war between Turkish security forces and Kurdistan Workers' Party (PKK) rebels after renewed violence shattered a truce in July.

Alarm bells are also ringing about the state of democracy in the country of 78 million following a string of high-profile police raids and prosecutions against media groups and journalists considered critical of Erdogan and his government.
