PARIS - French President Francois Hollande called on voters to back centrist Emmanuel Macron in the second round of the presidential election, warning of dangerous consequences if far-right candidate Marine Le Pen were to win. 'The presence of the far-right in the second round is a risk for the country,' Hollande said in a televised address. 'What is at stake is France's make-up, its unity, its membership of Europe and its place in the world.'
