The minute we start squabbling about what Ofsted say about face-coverings or about whether Muslim teachers should be allowed to wear them is the minute that Johnson has achieved his aim of injecting a little more Islamophobia into the argument. Muslim teachers' face-coverings in classrooms is a virtual non-issue that, should it ever arise, can be dealt with gently and amicably at local level. But he's got us bringing it up as though it was a serious and sinister matter. Nice one, Boris. The man has form and the injection of those remarks into his article was racist.
