London accuses China of hacking the data of 40 million Britons and calls it a "threat to national security" The United States and New Zealand also joined the complaint. They accuse her of launching a “prolific” global campaign of cyberattacks.

The attacks are directed at politicians, journalists, academics and millions of voters. The Chinese Foreign Ministry claimed Britain had provided insufficient evidence of the attacks. The attack on the Electoral Commission gave Chinese hackers access to the names and addresses of more than 40 million people on the electoral roll.
