Australia's privacy regulator is taking Facebook to court over the Cambridge Analytica scandal.The Office of the Australian Information Commissioner said Facebook had seriously infringed the privacy of more than 300,000 Australians.
The social media giant left personal data "exposed to be sold and used for... political profiling".
The scandal involved harvested Facebook data of 87 million people being used for advertising during elections, reports BBC.
"Facebook failed to take reasonable steps to protect those individuals' personal information from unauthorised disclosure," the Australian commissioner's office said.
Australia's federal court can impose a fine of A$1.7m (£860,000) for every serious or repeated interference with privacy, it added.
