Can the U.K. Remain United Without the Queen?

The funeral of Queen Elizabeth today will be one of the most extraordinary public spectacles of the last several decades in Britain, accompanied by an outpouring of sadness, reverence and respect. But the end of the queen’s 70-year reign has also prompted long-delayed conversations about the future of the Commonwealth and of the four nations that make up the United Kingdom. Guest: Mark Landler, the London bureau chief for The New York Times.
