It will come as no surprise to anyone that in Europe, the country that speaks English the best and the most is the United Kingdom, though it’s not the only language here. Immigration has brought many other languages, so that, alongside other local languages such as Welsh and Cornish, 8% of the population speaks a language other than English (though, of course, they may speak English as well).
However, on the continent, the number one spot is taken by Sweden where, according to novinite.com, 91% of the population is fluent in English. The Netherlands is close behind with a whopping 90% of the population who can speak English. Proof of how fluent they are here is that English-language films aren’t shown with subtitles – which may go a long way in explaining why their accent leans towards North America.
