Google has been fined 100 million euros (£91m) in France for breaking the country's rules on online advertising trackers known as cookies.

Axar.az reports that it is the largest fine ever issued by the French data privacy watchdog CNIL.

US retail giant Amazon was also fined 35 million euros for breaking the rules.

CNIL said Google and Amazon's French websites had not sought visitors' consent before advertising cookies were saved on their computers.

Google and Amazon also failed to provide clear information about how the online trackers would be used, and how visitors to the French websites could refuse the cookies, the regulator said.

It has given the tech giants three months to change the information banners displayed on their websites.
