Mark Zuckerberg declines to give evidence in UK Parliament

In the wake of the Cambridge Analytica revelations, Parliament's fake-news inquiry wants to hear from Zuckerberg in person, and it's not giving up yet.

Mark Zuckerberg turned down an opportunity to come to London to give evidence in Parliament about Facebook's part in the Cambridge Analytica scandal.

Zuckerberg said last week he would be happy to testify in front of Congress in the US. But the Facebook CEO will not be doing the same in the UK, according to a letter the company sent Monday to the chair of the Digital, Media, Culture and Sport Committee, Damian Collins.

In his place, Facebook offered up Chief Technology Officer Mike Schroefper or Chief Product Officer Chris Cox.

Collins wrote to Zuckerberg last week asking him to appear before the committee in person as part of Parliament's ongoing inquiry into fake news. Facebook already provided evidence as part of the inquiry in a session in Washington DC in February, but Collins was dissatisfied, accusing the company's representatives of consistently understating risks and "misleading" the committee.

He requested further evidence following the revelations last week that the personal data of up to 50 million Facebook users had been misused as part of work done by data consultancy firm Cambridge Analytica, best-known for its efforts on behalf of Donald Trump's election campaign.

"It is now time to hear from a senior Facebook executive with the sufficient authority to give an accurate account of this catastrophic failure of process," said Collins in his letter. "Given your commitment at the start of the New Year to 'fixing' Facebook, I hope that this representative will be you."

Collins' request isn't the only invitation that's been sent Facebook's way. In the US on Monday, the Senate's judiciary committee invited Zuckerberg, along with the CEOs of Twitter and Google, to appear at an April 10 hearing on the future of data privacy in social media.

In spite of Zuckerberg's rejection of his invitation, Collins is still determined that the Facebook CEO should give evidence to the committee.

"We'd be very happy to welcome Mr Cox to give evidence," Collins on Tuesday in a statement during an evidence session. "However we would still like to hear from Mr Zuckerberg himself."

He would seek to clarify whether Zuckerberg could give still give evidence, either in person or via video link, he said.
