First presidential run-off as Argentina goes to the polls
People in Argentina are voting to choose a successor to President Cristina Fernandez de Kirchner in an election that could end twelve years of left-wing government.
Mrs Fernandez is barred by the constitution from seeking a third term, and her preferred candidate, Daniel Scioli, is facing a strong challenge from the opposition mayor of Buenos Aires, Mauricio Macri.
