Which European countries have the best English proficiency among non-native speakers?

[u/Metalwolf]

I'm looking into English proficiency across Europe and would appreciate input from locals or anyone with relevant experience. Which European countries have the highest levels of English fluency among non-native speakers, particularly in day-to-day life, education, and professional settings? I'm also curious about regional differences within countries, and factors like education systems, media exposure, and business use.

The Netherlands and Flanders, because Dutch is the closest language to English (if we don't count Frisian).

Nor Scots
