ANKARA

As Türkiye heads to presidential runoff election on May 28, President Recep Tayyip Erdogan on Tuesday vowed to win a landslide victory.

"Now is the time to crown the success we achieved on May 14 with a greater victory," Erdogan said on Twitter.

Millions of voters went to the polls on Sunday to elect the country's president and members of its 600-seat parliament.

Erdogan’s People’s Alliance won a majority in parliament, while the presidential race is headed to a second-round runoff on May 28, though Erdogan took the lead in round one.

Erdogan and his closest competitor Kemal Kilicdaroglu, leader of the main opposition Republican People's Party (CHP) and joint candidate for the six-party opposition Nation Alliance, will face off in round two.

"We are an alliance that puts the national will and the love of serving the country, and the nation at the center of its politics," Erdogan said.

He added that they can only repay debt of gratitude to the nation by working harder.

"Türkiye expects service from us, it expects action. Our nation expects us to meet its goals," he said.
