What percentage of Norwegian citizens speak English?

I couldn't find any official statistics. But English has been taught as a mandatory foreign language in Norwegian primary school since the 1960s, so close to 100% of the population below age 60 or so will know at least some English. Before the 1960s, English was taught in secondary school.

According to Wikipedia, 89% of the population of Sweden speaks English. I assume the percentage for Norway is about the same.
