Shopping in Harrods last week, I came across a group of women wearing black burkhas, browsing the latest designs in the fashion department.
The irony of the situation was almost laughable. Here was a group of affluent women window shopping for designs that they would never once be able to wear in public.
Yet it's a sight that's becoming more and more commonplace. In hardline Muslim communities right across Britain, the burkha and hijab - the Muslim headscarf - are becoming the norm.
