I came across an article the other day titled "Learn English or stay home". It was written by Olav Øye for the European Voice website, but unfortunately sits behind the paywall. According to the byline, Øye is a consultant and has dedicated his masters thesis ("E pluribus English") to the study of how English is used in the European Parliament. There has been much discussion in recent months and years about the role of English and the question whether it should and could become the one and only lingua franca of the Union. I think there's no easy answer to that question.
