LONDON — With Kemi Badenoch settling in as the new leader of the Conservative Party we might spare a thought for Suella Braverman, who may well go down in history as the great lost leader of the United Kingdom. Mrs. Braverman withdrew from the contest in the summer on the grounds that her party did not want to hear the truth about why it had lost the election, much of which she believed was down to its failure to stop the out-of-control level of illegal immigration now affecting this small island.
