Mandarin has the most speakers. English is the most widely spoken.
English is the most spoken language in the world because of the historical influence of the British Empire and later the United States as global superpowers. It is also widely used as the language of business, science, and technology, making it a common second language for many people globally. Additionally, the spread of English through media, entertainment, and the internet has further solidified its position as a global lingua franca.
