Brittany Kaiser, who spoke out in March, among those appearing in front of fake news inquiry

A series of senior figures linked to the Cambridge Analytica scandal are to appear in front of the House of Commons inquiry into fake news and misinformation, the digital, culture, media and sport committee has announced.

Brittany Kaiser, a former business development director at Cambridge Analytica, will speak to the committee on 17 April. Kaiser worked to find new clients for the election consultancy and spoke out in March about her role at Cambridge Analytica.

“I’m so tired of making excuses for old white men,” she said when she went public. “There’s a much wider story that I think needs to be told about how people can protect themselves, and their own data.”

The day after Kaiser, Alexander Nix, the former Cambridge Analytica chief executive, will return to speak in front of the committee for a second time on 18 April. He was publicly recalled to the committee last month due to “inconsistencies” in his earlier evidence.

The committee chair, Damian Collins, wrote: “Following material published in the UK Guardian, the New York Times and Channel 4 over the past few days, the committee would like to request that you supply further evidence.

“We are also interested in asking you again about your claim that you ‘do not work with Facebook data, and … do not have Facebook data’.”

Collins warned Nix that “giving false statements to a select committee is a very serious matter” and urged him to “explain” his comments.

Aleksandr Kogan, a Cambridge University academic responsible for building the “thisisyourdigitallife” Facebook application, will appear in front of the committee on 24 April. The application harvested the data of 87 million Facebook users that ultimately ended up in the hands of Cambridge Analytica.

Finally, on 26 April , Facebook will appear in front of the committee. Although Mark Zuckerberg has repeatedly been invited, and will testify before the US Congress on 11 April, he will not be speaking to the UK parliament. Instead, he is sending Mike Schroepfer, Facebook’s chief technology officer.

Facebook had initially offered Schroepfer and Chris Cox, the company’s chief product officer, and the committee had requested the presence of Cox, but following Schroepfer’s presence at the head of the response, Facebook decided to send him instead.

Speaking in March, Collins said: “I think … it is absolutely astonishing that Mark Zuckerberg is not prepared to submit himself to questioning in front of a parliamentary … hearing, given these are questions of fundamental importance and concern to his users, as well as to this inquiry.”
