Voting is underway in Turkey's presidential election. Attention is focused on whether Recep Tayyip Erdogan can continue his long run of power.

The race is seen as a head-on clash between Erdogan and Kemal Kilicdaroglu, the leader of the largest opposition party. Kilicdaroglu is the joint candidate of six opposition parties.

Erdogan has served as prime minister or president for a total of 20 years. Last year, he helped broker a deal that allowed Ukrainian farm products to be exported through the Black Sea. The exports had stopped due to Russia's invasion of Ukraine.

Kilicdaroglu has been highlighting the plunge of the lira, Turkey's currency, and an increase in prices under the current administration.

He has criticized the government for delays in its initial response to the major quakes in February. He has also accused the government of allowing the construction of buildings that did not meet quake-resistance standards. The opposition leader has vowed to improve Turkey's relations with Western nations, which soured under Erdogan.

Ballots will be counted on the same day. If none of the candidates secures a majority, a run-off election will be held between the top two contenders on May 28.
