Is Prince Harry blackmailing his family?

For all of the noise that Prince Harry has made over the past few days (weeks, months, and years) about his loathing of the British media, he knows – or has been made aware by his publishers – of the necessity of sitting down with journalists in order to promote his book. And so it is that, yielding to the entreaties of publicity, he has been interviewed by the estimable Bryony Gordon for the Telegraph. It’s an interesting feature, full of colour and anecdote, and demonstrates, as if it needed to, that the rebellious prince remains a source of endless fascination to everyone in his former home country.

Yet the piece is dominated by one news line: Harry’s revelation that he has at least another book’s worth of considerably more scandalous material, which was dropped from his memoir for fear of causing irreconcilable offence, and his implicit threat that it could yet be published.
