Results, candidates, agenda: Turkey election run-off in 400 words

People across Turkey are casting their ballots in the country’s presidential election run-off.

Here is all you need to know.Recep Tayyip Erdogan, 69, seeks to extend his 20 years in power by a further five years.
He faces 74-year-old Kemal Kilicdaroglu, the main opposition candidate.
In the first round on May 14, Erdogan gathered nearly 50 percent of the vote, followed by Kilicdaroglu at about 45 percent.
Sinan Ogan, an ultranationalist who was eliminated from the run-off after coming third with some 5.2 percent, has thrown his weight behind Erdogan.
Sunday is the first time Turkish voters have ever had to go to the ballot box for a second time to pick their next president.
The polls opened at 8am (05:00 GMT) and will close at 5pm (14:00 GMT).
Turnout has been strong since the opening of the polls and observers expect voter participation to be high.
It remains to be seen, however, if it will reach the 89 percent of the first round.
As on May 14, Turkish citizens living abroad completed casting their ballots before election day. Some 1.9 million voted in 73 countries and at border gates.
Both Erdogan and Kilicdaroglyu have voted, the former in Istanbul and the later in Ankara.
With just two candidates facing off, it is widely expected that results will be available sooner than the first round – possibly in the evening.
The voting has so far gone off without any problems, according to electoral officials.
In the lead-up to the first round, the agenda was largely centred on the state of the Turkish economy and the response to February’s devastating earthquakes that killed tens of thousands of people in the country’s south and southeast.
But the agenda shifted notably after the first round, with topics such as the fate of refugees in the country and “terrorism” largely dominating the campaign.
Erdogan’s Justice and Development Party (AK Party), along with its allies, secured a majority in the parliamentary polls that were also held on May 14.
Interestingly, the AK Party came first in 10 of the 11 provinces struck by the earthquakes.
In Sunday’s run-off, the number of voters has been boosted by more than 47,500 voters who turned 18 over the past two weeks, taking the electorate in Turkey to almost 60.8 million.
