Turkey's biggest opposition party leader is warning the ruling party to stick to the rule of law after its stunning return to one-party rule in Turkey's parliament.

Kemal Kilicdaroglu, leader of the secularist CHP says: "The party in power has to respect the principle of the supremacy of the law."

Sunday's vote was a rerun of a June election in which the ruling Justice and Development party, or AKP, surprisingly lost its one-party rule. CHP improved its vote tally on Sunday, but not nearly as dramatically as AKP.

Kilicdaroglu said: "We increased our votes, but we don't consider this as an achievement. Coming to power would have been an achievement."

He added that the results may have been very different but for the spate of recent violence that has rocked Turkey.

The leaders of Turkey's pro-Kurdish party say that unfair election conditions explain their drop-off in Sunday's parliamentary elections.

The pro-Kurdish People's Democratic Party, or HDP, was forced to cancel election rallies following two deadly attacks on pro-Kurdish gatherings since July. Television stations gave party representatives little air-time amid government attacks branding the party as the political wing of the Kurdistan Workers' Party, or PKK, which is considered a terrorist organization by Turkey and its allies.

HDP's co-chairman Selahattin Demirtas told reporters that "there wasn't a fair or equal election... We were not able to lead an election campaign. We tried to protect our people against attacks."

Following the vote Sunday, small clashes broke out in Diyarbakir in the Kurdish southeast between protesters and police.

Turkey's Prime Minister Ahmet Davutoglu has declared victory for his ruling party after preliminary election results showed it restoring its majority in parliament.

State-run TRT television reports that with more than 95 percent of the votes counted, the ruling Justice and Development Party, or AKP, has won just above 49 percent, which would comfortably restore its ruling majority.

Davutoglu said: "Today is the day of victory of democracy and the people."

The results suggest that AKP's gamble to hold new elections has paid off. Supporters at the party's Ankara and Istanbul headquarters were already waving flags in rapturous celebrations.

The vote is a rerun of a June election in which AKP surprisingly lost its one-party rule due to a strong showing by a Kurdish party.
