Colombians are set to vote in the final round of the country's presidential election on Sunday.

The race pits conservative Juan Manuel Santos, the former defence minister, against Antanas Mockus, the leftist former mayor of Bogota.

Whoever wins the race will have to deal with ongoing rebel confrontations, improving diplomatic ties with Venezuela and soaring unemployment.
