>> The two ex-Prime Ministers vying to be France's President, casting their votes on Sunday in the final run off to decide who will spearhead the center right in next year's crunch election. François Fillon is the surprise frontrunner, defying pollsters to win the first round of voting last week, knocking out his former boss, Nicholas Sarkozy.
The social conservative has promised a radical overhaul of the French economy, vowing to slash government spending.>>
> His most centrist opponent, Alain Juppe, has scrambled to regain momentum over the past week, describing Fillon's plan as brutality. With the ruling socialists in disarray, whoever wins is likely to go up against a resurgent far right led by the National Front's Marine Le Pen.
Opinion polls currently suggest Le Pen would lose that battle, but pollsters have lost credibility since the UK's Brexit boot and Donald Trump's shock triumph. And with some six months to play out, there's still plenty of time for another upset.
