Up to 44 million UK Facebook users could share £2.3bn in damages, according to a competition expert intending to sue parent company Meta.

Facebook's WhatsApp was fined a record 225 million euro by the Irish data protection regulator on Thursday after the EU privacy watchdog pressured Ireland to raise the penalty for the company's privacy breaches.

Partly at issue is how WhatsApp share information with parent company Facebook, according to the commission. The decision brings an end to a GDPR inquiry the privacy regulator started in December 2018. WhatsApp said it disagrees with the decision and plans to appeal. "We have worked to ensure the information we provide is transparent and comprehensive and will continue to do so," a WhatsApp spokesperson said via email.

Amazon announced that it has been fined 746 million euros for violating the EU's General Data Protection Regulation (GDPR) rules on how to process personal data. The notice, buried within the latest SEC filing from Amazon, said the decision was made by the Luxembourg National Commission (CNPD) for Data Protection on July 16. Alongside the fine, Amazon said the decision also imposes "corresponding practice revisions."
