The Wikipedia article you linked to gives that as one option for the article. About the only one that England qualifies as a nation for is common language but last time I went to Scotland the people there were speaking English too. Sure they used some different words and accents but so does my nephew in Devon.
My point is I don't believe England exists as a nation and neither do the other home nations. They are geographic areas that some politicians use to further their careers.
