Are Russian hackers trying to help Le Pen win French election? Front-runner Macron claims his campaign has suffered 'massive and co-ordinated' email leak on the eve of vote as polls put him 24 points ahead

Hacked documents from Emmanuel Macron's presidential campaign were posted online last night in a 'massive and co-ordinated attack' after the front-runner complained of Russian attempts to destabilise him. Some nine gigabytes of data were posted by a user called EMLEAKS to Pastebin, a document-sharing site that allows anonymous posting. They included emails, accounting documents and contracts - all legal - from his campaign. Macron's political movement En Marche! (Onwards!) said that several of its leaders had their emails hacked. Former economy minister Macron's team has complained in the past about attempts to hack its emails during a fraught campaign, blaming Russian interests in part for the cyber attacks. President Vladimir Putin is said to favour anti-EU candidate Le Pen whose election would contribute to the further destabilisation of the Union.
