Wherever the headline comes from, here's the reference to language [emphasis added]:
Across the English-speaking world, immigrants are drawn by the same things: relatively strong economies, good universities, open cultures and the world’s lingua franca.

*Answer to question: Lingua franca is English / in English. Wasn't always English, but is now.
