Facebook has received a £500,000 fine from the UK’s data protection watchdog for failing to protect users’ info or tell them how their data will be harvested.

The promised penalty relates to the social media giant's role in the Cambridge Analytica data harvesting scandal, which saw the personal information of some 87 million users’ information sucked up and shared by an app developer.
