Ecuadorians head to the polls this Sunday, in one of the most hotly contested elections in decades. Thirty-seven-year-old President Daniel Noboa, the son of a banana tycoon, is facing off against former National Assembly member and leftist Luisa González. Security is the top issue on the table, as both candidates promise to tackle the rising narco-gang violence that has given Ecuador one of the highest homicide rates in Latin America. Michael Fox has the story from the capital, Quito.
