But it seems that the truth could not be more different.
Yesterday the 9th Earl Spencer, now 53, reopened hostilities in an emotional interview on Radio 4’s Today programme.
He had been a ‘passionate advocate’ of them not walking, but ‘eventually I was lied to and told they wanted to do it, which of course they didn’t, but I didn’t realise that’.
But why did Lord Spencer so pointedly make this embarrassing disclosure during an interview in which some listeners may have detected overtones of the infamous BBC Panorama programme in which Diana painted herself as a victim while slipping a stiletto between the ribs of her estranged husband Charles.
Senior police officers feared that in the atmosphere of hostility towards the royals, and Prince Charles in particular in the immediate aftermath of Diana’s death, there could be demonstrations against the walking Prince Charles which might even endanger him.
