Emmanuel Macron's campaign hacked on eve of French election

En Marche! movement says posting of huge email leak online 'clearly amounts to democratic destabilisation as was seen in the US'

The French presidential candidate Emmanuel Macron has been targeted by a "massive and coordinated" hacking attack, according to his campaign team, hours before voters go to the polls.

Macron, who opinion polls suggest should win Sunday's vote by 60% to his rival Marine Le Pen's 40%, was unable to respond to the alleged attack due to a ban on electioneering in the run-up to the opening of polling stations.
