I would like to offer two observations.
1. We use the term English to describe the words used.
2. An English person is likely to find someone speaking the language with an accent more interesting than a native person in many cases so it is not necessarily a disadvantage.
I would say that the language we refer to as English is also American, Australian, South Africa (ish) and others. It may have it's roots in England but it is no longer ours. There are many contributors to this from my perspective (Internet, US TV etc etc) but I don't think it is fair to say that the EU will stop speaking English because we leave the party. It is a bigger thing than just Britain. Lets face it they don't even use it in Sunderland
