Google has added its fact check feature to search results globally, in a bid to help tackle the spread of "fake news". The search giant will now highlight "authoritative sources" in search results, with a summary of claims that have been fact-checked. Google says sites will be judged authoritative by an algorithm and the company will not be fact-checking news stories itself. It follows a Facebook campaign to help people spot fake news.
