A third of schools in Blackburn and Leicester have a non-English speaking majority
while in Birmingham that figure is about a quarter

There's one false fact for a start. If you look at the footnote given, you will see that the figures about those for whom English is not a mother tongue....not non-English speaking people. Elsewhere bi-lingualism is celebrated as an achoievement.

Thw whole report seeks to colour the facts by using ambiguous and misleading language.
