A conservative veteran is taking on a left-leaning independent in Cyprus' presidential runoff amid questions whether an agreement reunifying the ethnically divided island-nation can be found anytime soon.

The choice for some 551,000 eligible voters Sunday will also depend on which candidate they feel has made the most convincing pitch to deliver more benefits from a rebounding economy.

It's the second time incumbent President Nicos Anastasiades faces off against independent Stavros Malas in a runoff.

Earlier opinion polls have shown Anastasiades handily beating Malas, but the independent's strong showing in the first round could make it a closer race.

Anastasiades says Cyprus needs more of his experienced leadership to stay the course. Malas says change is needed to raise the standard of living.
