It's late in the day (no, not literally, but for Britain), but I do think that Charles Moore, as so often, has some good things to say:

Teach English, Restore Parliament, Look again at the word 'Britain'.

Yes, and we could forget the Notting Hill Carnival without loss (no offence to people of African or Carribean origin, but it's a farce, isn't it, which will dwindle by itself being contentless already?). In addition to reviving Parliament we could give some teeth to the law by reviving the death penalty for murder. It's not really that radical to suggest that we take ourselves, our language, our society, and, yes, our 'communities' a little more seriously.
