The whistleblower at the heart of the Facebook scandal believes the UK wouldn't have voted for Brexit without Cambridge Analytica's intervention. DW looks at the ties between the Brexit campaign and consulting company.
Whistleblower Christopher Wylie told UK lawmakers during a committee hearing on Tuesday that a firm linked to Cambridge Analytica helped the official Vote Leave campaign circumvent campaign financing laws during the Brexit referendum.
Leaked documents published this week show that the Vote Leave campaign, the official pro-Brexit group headed by Boris Johnson and Michael Gove, paid an additional 625,000 pounds (€711,000, $882,000) to a little-known Canadian data firm called AggregateIQ (AIQ) through a far smaller pro-Brexit group.
The Vote Leave campaign has claimed that the payment to the smaller group, known as BeLeave, was a donation and that each group worked independently from one another.
However, documents leaked last weekend by whistleblower Shahmir Sanni, showed that the Vote Leave and BeLeave were effectively the same entity, with the latter even located inside the former's offices.
Wylie said on Tuesday that BeLeave, which was founded by 22-year-old fashion student Darren Grimes, was effectively used as a money laundering vehicle.
Campaign finance records showed that BeLeave spent the 625,000-pound donation on services from AIQ just days before the referendum vote.
Wylie said that the official campaign's "cheating" may well have swayed the EU referendum result given the effectiveness of AIQ's online campaign.
Overall, various pro-Brexit group spent 3.4 million pounds for AIQ's services during the EU referendum campaign. Some 2.7 million pounds of that money was spent by Vote Leave, making up 40 percent of the group's campaign budget.
However, Wylie said he was "absolutely convinced" Vote Leave also worked with other groups to circumvent campaign spending rules.
"I am absolutely convinced that there was a common plan and common purpose with Vote Leave, BeLeave, the DUP, and Veterans for Britain. All of these companies somehow, for some reason, all decided to use AIQ," he said. "When you look at the accumulation of evidence, I think it would be completely unreasonable to come to any other conclusion other than this must be coordination, this must be a common purpose plan."
IQ and Cambridge Analytica
Officials from AIQ and Cambridge Analytica have denied the two companies coordinated during the Brexit referendum.
However, Wylie told the UK parliamentary committee that AIQ, which he says he helped create on behalf of SLC, the parent company of what would eventually become Cambridge Analytica, frequently shared data with one another during the EU referendum campaign.
"You can't have targeting software that doesn't access the database. Cambridge Analytica would have a database and AIQ would access that database, otherwise the software wouldn't work," Wylie said.
Wylie also said that AIQ, when it was set up, inherited Cambridge Analytica's total disregard of the law.
Referring to a campaign AIQ worked on in Nigeria, the Cambridge Analytica whistleblower said: "This is a company that has worked with hacked material, this is a company that will send out videos of people being murdered to intimidate voters, this is a company that goes out and tries to illicitly acquire live internet browsing data of everyone in an entire country."
Mark Zuckerberg refuses to testify before UK Cambridge Analytica enquiry
Facebook boss Mark Zuckerberg on Tuesday said he would not appear before the British parliamentary committee to explain how the profiles of some 50 million users were harvested by Cambridge Analytica.
The Facebook CEO instead offered to send chief technology office Mike Schroepfer or chief product officer Chris Cox to answer lawmakers' questions in London next month.
Committee chairman Damian Collins urged Zuckerberg to reconsider, given the seriousness of the allegations.
"We'd be very happy to invite Mr Cox to give evidence. However we would still like to hear from Mr Zuckerberg as well," Collins said at the start of Wylie's committee hearing.
Facebook insists it didn't know that Cambridge Analytica had harvested data from millions of users through an app, which was subsequently leveraged by Donald Trump's presidential campaign team.
