Hi, for free articles I normally use The Guardian (UK) for my students. For cheap paid articles, I’d recommend The New York Times, whereas if you want paid but well-written articles, go for The Economist (you get 5 articles per month if you sign up). There are other great news sites (National Geographic, Wall Street Journal, etc.) but I mostly use these three platforms for my students because the articles are well-written (C1-C2 English)
