“This latest data breach – potentially affecting the personal photos of millions of people – will cause real concern and distress to some Facebook users and further erode confidence in the social network after the Cambridge Analytica scandal.

“If Facebook is to restore the trust of its users, it must show that it is putting them first by getting to grips with how their data is shared with third-party apps and advertisers – and regulators must be prepared to take tough action when tech firms fail to protect users’ personal data.”
