Facebook CEO admits mistakes
Zuckerberg admits 87m users hit by data scandal
Shares in Facebook have fallen more than 16% since the scandal broke over Cambridge Analytica accessing the data of Facebook users to use in political campaigning.
Chief executive Mark Zuckerberg admitted that the personal information of up to 87 million users, mostly in the United States, may have been improperly shared with London-based consultancy. It is estimated that about one million of the affected users are in the UK.
He told reporters on a conference call that Facebook had not seen “any meaningful impact” on usage or advertising sales since the scandal.
He accepted blame for the data leak, which has led to calls for a boycott by users and advertisers.
Mr Zuckerberg insisted he was still the right person to head the company he established and that he would learn from his mistakes.
Mr Zuckerberg will give evidence to two US congressional hearings next Tuesday and Wednesday. He has declined to answer questions from British MPs.
Cambridge Analytica disputed the figures, saying on Twitter it had received no more than 30 million records from a researcher it hired to collect data about people on Facebook.
The company will be adding a new app to control third party access to information.
