Cambridge Analytica: Facebook row firm boss suspended
Cambridge Analytica, the firm involved in a row over its use of Facebook data, has suspended its boss Alexander Nix.
The chief executive's comments, secretly recorded by Channel 4 News, "do not represent the values or operations of the firm," it said.
In the footage, Mr Nix appeared to suggest tactics his company could use to discredit politicians online.
However, Cambridge Analytica said the report had "grossly misrepresented" the conversations caught on camera.
The London-based firm, along with the social network, is under scrutiny following claims by a whistleblower, Christopher Wylie, who worked with Cambridge Analytica.
He alleges it amassed large amounts of data through a personality quiz on Facebook called This is Your Digital Life.
He claims that 270,000 people took the quiz, but the data of some 50 million users, mainly in the US, was harvested without their explicit consent via their friend networks.
Mr Wylie says that data was sold to Cambridge Analytica, which then used it to psychologically profile people and deliver pro-Trump material to them, with a view to influencing the outcome of the 2016 presidential election.

Facebook has said the data was obtained legitimately, but Cambridge Analytica failed to delete it when subsequently ordered to do so.
For its part, Cambridge Analytica says it deleted the data when Facebook told it to.
Facebook said on Tuesday that the entire company was "outraged we were deceived".
"We are committed to vigorously enforcing our policies to protect people's information and will take whatever steps are required to see that this happens," it added.
The firm will send representatives to Washington on Wednesday to answer questions before the US Congress.
Filming by Channel 4 News, broadcast on Tuesday, showed Mr Nix claiming his firm had run Mr Trump's digital campaign.
He said that the work the company did, including research, analytics and targeted campaigning, allowed the Republican candidate to win with a narrow margin of "40,000 votes" in three states.
"We did all the research, all the data, all the analytics, all the targeting, we ran all the digital campaign, the television campaign and our data informed all the strategy," he added.
A statement from Cambridge Analytica's board of directors said Mr Nix had been suspended with "immediate effect, pending a full, independent investigation".
It added: "In the view of the board, Mr Nix's recent comments secretly recorded by Channel 4 and other allegations do not represent the values or operations of the firm and his suspension reflects the seriousness with which we view this violation."
The firm's chief data officer, Dr Alexander Tayler - who was also filmed discussing campaign strategy for Mr Trump - will serve as acting CEO.
'Send some girls'
The undercover report shown on Monday saw Mr Nix describing how he could target individuals.
He said one way was to "offer them a deal that's too good to be true and make sure that video's recorded".
He also said he could "send some girls around to the candidate's house..." adding that Ukrainian girls "are very beautiful, I find that works very well".
Mr Nix continued: "I'm just giving you examples of what can be done and what has been done."
The managing director of Cambridge Analytica's political division, Mark Turnbull, was also shown saying the company could create proxy organisations to spread negative material about opposition candidates online without being traced.
On Monday, Cambridge Analytica said the executives had "entertained a series of ludicrous hypothetical scenarios" in order to "play along with this line of conversation, and partly to spare our 'client' from embarrassment".
And Mr Nix told the BBC's Newsnight programme he felt the firm had been "deliberately entrapped".
There have now been calls for an investigation into the work Cambridge Analytica carried out during the 2013 election in Kenya.
Earlier, a parliamentary committee called for Facebook CEO Mark Zuckerberg to give evidence about the use of personal data by Cambridge Analytica.
Damian Collins, the chairman of the Commons inquiry into fake news, accused Facebook of "misleading" the committee previously, and said it was "now time to hear from a senior Facebook executive with the sufficient authority to give an accurate account of this catastrophic failure of process".
Facebook shares fell by a further 5% on Tuesday, following a 6.7% drop on Monday, meaning that in total, about $50bn has been wiped from its market value.
The company held an open meeting with its employees on Tuesday to discuss the matter, but the BBC's North America technology reporter Dave Lee said neither Mr Zuckerberg nor his deputy, Sheryl Sandberg, chaired it.
Facebook said: "Mark, Sheryl and their teams are working around the clock to get all the facts and take the appropriate action moving forward, because they understand the seriousness of this issue."
The UK's Information Commissioner Elizabeth Denham said she would be applying to court for a warrant to search the offices of Cambridge Analytica.
The consumer watchdog the US Federal Trade Commission - which has the power to levy large fines - has also reportedly opened an investigation into Facebook.
Dr Aleksandr Kogan, who created the personality app from which the data had been harvested, is a senior research associate at the University of Cambridge.
A spokesman from the university said they had "sought and received assurances" from Dr Kogan that no University data, resources or facilities were used for his work and they had found no evidence to contradict that, but were writing to Facebook to "request all relevant evidence in their possession".
