Macron allies warn victory not certain as poll lead over Le Pen grows

Centrist's backers say voters still need convincing his policies are best for them ahead of presidential runoff

Senior political allies of Emmanuel Macron have lined up to warn against complacency in France's presidential race, saying the incumbent is not certain to win despite polls indicating his lead over his far-right challenger, Marine Le Pen, is widening.
