My hon. Friend raises a very important point. Matters of school uniform are rightly questions that head teachers should decide on, or college principals should be responsible for. I hope it is clear that the wearing of any item that impedes effective teaching or effective learning is something that we should all ensure does not happen in the classroom. I am working with both the chief inspector of schools and officials within the Department for Education in order to ensure that schools and individuals receive an unambiguous message about the vital importance of ensuring that cultural or other barriers do not impede the capacity to learn of children from whatever community.
