The UK Supreme Court has blocked a planned 3.2 billion pound ($4.3 billion) British class action against Google over allegations the internet giant unlawfully tracked the personal information of millions of iPhone users.

In a hotly-anticipated judgment, Britain's top judges on Wednesday granted a Google appeal against the country's first such data privacy case in a move that upsets a string of similar claims against technology giants such as Facebook and TikTok, already waiting in the wings.
