Always difficult when it comes to ruling on cultural or religious forms of dress because it is about being able to justify banning such items in the face of those calling it out as discrimination. There are no good arguments for banning turbans for example or hijabs and any H&S issues can be worked around. Niqabs (if not also veiled) I don't have an issue with but I do think that Burkas are problematic.

Whilst totally agreeing with Al's view that they are a method of controlling women in highly patriarchal societies, the vast majority who wear them doubtless pose no threat but any such form of concealment clearly has the potential to do so. Just as there are justifiable reasons to ban the wearing of hoodies or helmets in certain spaces to stop those wanting to avoid identification, the same should apply to Burkas. We are not an Islamic country where the culture insists that women wear them in public and are not under any obligation to do so.
