Diana died because her driver was drunk. Everybody knows this now, and indeed everybody knew it at the time. If Fayed wants to pursue his conspiracy theories any further, then he should be made to do so at his own expense, not ours.
How many people must there be who have lost loved ones in circumstances that they feel have never been properly explained, and which very well might not have been? And how many of them have been refused naturalisation in this country, but nevertheless granted endless inquests at the British taxpayer's expense?
Why would anyone have wanted to murder Diana, anyway? Following her divorce, she was a peripheral figure of no importance whatever except to followers of celebrity tittle-tattle. By now, she would have been just another has-been swanning around California.
