Facebook and CEO Mark Zuckerberg has faced intense scrutiny after Cambridge Analytica obtained the personal information of as many as 87 million Facebook users. Studies have focused on how the data was used.
Facebook will also gain access during the settlement of documents obtained by the British government from Cambridge Analytica, which the company said they will use to investigate the matter further.
Harry Kinmonth, Facebook's attorney, said in a statement that the company wished it "had done more to investigate allegations of Cambridge Analytica in 2015," and that it had made "major changes."
"Protecting people's information and privacy is a top priority for Facebook, and we continue to build new controls to help people protect and manage their information," Kinmonth said.
ICO Deputy Commissioner James Dipple-Johnstone said in a statement that the protection of personal data is "fundamental" for "preserving a strong democracy. "
" We are pleased to hear that Facebook has taken and will continue to take important steps to comply with the basic principles of data protection, "he added.
