One day the royal family in England will be islamic... or else ... So Kate should start wearing the black body bag.
As long as Elizabeth lives, England will be CoE. With Charles in charge? I believe you may be correct. Skip a generation to William and they may have a chance! I’m sure that Henry (Prince Harry), the Prince of Wales (aka Captain Wales (ret), Blues and Royals) would quickly explain to ‘older brother’ the folly of any FURTHER moslemification of England. Remember, Prince Harry served several tours in Afghanistan and his private views on the ‘stan are likely stated more strongly in private than in public.
