An academic who created an app which harvested data from 50 million users says he has been made “a scapegoat” for Facebook and Cambridge Analytica.
Dr Aleksandr Kogan said he did not know his work for Cambridge Analytica in 2014 violated Facebook’s policies.
Cambridge Analytica, which worked on Donald Trump’s US election campaign, also approached the Conservatives under David Cameron’s leadership.
The party had rejected its pitch for work, a No 10 spokesman said.
The Ministry of Defence, Home Office and Foreign Office previously had contracts with Cambridge Analytica’s parent company SCL, but they ended well before the current issues, Downing Street said.
Theresa May, speaking during Prime Minister’s Questions earlier, said the allegations were “clearly very concerning” and should be “properly investigated”.

What is the row about?
In 2014, Facebook invited users to find out their personality type via a quiz developed by Cambridge University researcher Dr Kogan called This is Your Digital Life.
About 270,000 users’ data was collected, but the app also collected some public data from users’ friends.
Facebook has since changed the amount of data developers can gather in this way, but a whistleblower, Christopher Wylie, says the data of about 50 million people was harvested for Cambridge Analytica before the rules on user consent were tightened up.
Mr Wylie claims the data was sold to Cambridge Analytica – which has no connection with Cambridge University – which then used it to psychologically profile people and deliver pro-Trump material to them.
The firm’s chief executive Alexander Nix – who was suspended on Tuesday – was secretly recorded in a Channel 4 investigation saying the London-based company ran Donald Trump’s digital campaign during the 2016 US election.
“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.
What does Dr Kogan say about his involvement?
The academic told BBC Radio 4’s Today programme the events of the past week had been “a total shell shock”.
“My view is that I’m being basically used as a scapegoat by both Facebook and Cambridge Analytica when… we thought we were doing something that was really normal.
“We were assured by Cambridge Analytica that everything was perfectly legal and within the terms of service.”
He said he was following advice given to him by the UK-based consultancy, but added: “One of the great mistakes I did here was I just didn’t ask enough questions.”
He also said the accuracy of the dataset had been “exaggerated” by Cambridge Analytica, and had been more likely to hurt than help Mr Trump’s campaign.
What investigations are under way?
The UK’s Information Commissioner Elizabeth Denham is attempting to obtain a warrant to search the offices of Cambridge Analytica.
Meanwhile, a UK parliamentary committee has called for Facebook boss Mark Zuckerberg to give evidence about its use of personal data.
Damian Collins, the chairman of the Commons inquiry into fake news, accused Facebook of previously “misleading” the committee, 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”.
US senators have called on Mr Zuckerberg to testify before Congress about how his company will protect users, while consumer watchdog the US Federal Trade Commission has also reportedly opened an investigation into Facebook.
The head of the European Parliament also said it would investigate to see if the data was misused.
On Tuesday a Cambridge University spokesperson 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”.
There have also been calls for an investigation into the work Cambridge Analytica carried out during the 2013 election in Kenya.
How have Facebook and Cambridge Analytica responded?
Both Cambridge Analytica and Facebook deny any wrongdoing.
Facebook says users’ data was obtained legitimately but Cambridge Analytica failed to delete it when told to do so.
A Facebook spokesperson said Dr Kogan was not allowed to transfer data to Cambridge Analytica, a third-party who would use the set for commercial purposes.
They added that sharing users’ friends data outside the app was also against Facebook’s rules.
For its part, Cambridge Analytica says it did delete the data when told to by Facebook.
It suspended Mr Nix following his comments which appeared to suggest tactics his company could use to discredit politicians online.
However, the firm said the report of comments secretly recorded by Channel 4 News had “grossly misrepresented” Mr Nix’s comments.
Before Channel 4 News had broadcast any of the secret filming, Mr Nix told the BBC’s Newsnight programme he felt the firm had been “deliberately entrapped”.
What does Cambridge Analytica do?
On its website, it says: “Our team of PHD data scientists, expert researchers, and seasoned political operatives have produced decisive results for campaigns and initiatives throughout the world.”
It had been credited with helping Donald Trump to presidential victory.
How do I protect my Facebook account?
- Log in to Facebook and visit the App setting page
- Click edit button under Apps, Websites and Plugins
This will mean that you won’t be able to use third-party sites on Facebook and if that is is a step too far, there is a way of limiting the personal information accessible by apps while still using them:
- Log into Facebook’s App settings page
- Unclick every category you don’t want the app to access, which includes bio, birthday, family, religious views, if you are online, posts on your timeline, activities and interests
There are some other pieces of advice too.
“Never click on a ‘like’ button on a product service page and if you want to play these games and quizzes, don’t log in through Facebook but go directly to the site,” said Paul Bernal, a lecturer in Information Technology, Intellectual Property and Media Law in the University of East Anglia School of Law.
