Fugitive couch-surfer and angry leaker Julian Assange has made the explosive claim that Cambridge Analytica asked WikiLeaks for something before last year's US presidential election.

Cambridge Analytica is known to have provided services to US president Donald Trump's campaign and is owned by investors including Robert Mercer, billionaire keen on conservative causes. The company's political services arm offers “data driven political campaigns”, and claims it will “find your voters and move them to action.”
