Have you been to Nigeria?
Not all Nigerians can speak English. But there are a lot who can. It honestly felt about 50/50 to me. And I see some other commenters saying that 60 million Nigerians have some ability to speak it. (But you need to think of that like if I was to say 60 million Americans have some ability to speak Spanish.)
However, even for those with some facility with English,I don't know that I'd classify it as their native language.
