No Henri, I am not 'implying it' I am suggesting that it might well be the case. I think that Charles Spencer could have asked the vicar etc to 'help his martyred sister have eternal rest with her ancestors' without danger of the loons, whether those that loved her or hated her, from desecrating her grave. I think, given the mood at the time, that there is very little that would have been refused the family. And there were,of course, no witnesses to the 'private' internment.
Of course there were witnesses - there were pallbearers who transported & lowered the coffin into the army-prepared grave. There were the family who accompanied it to the island and all the estate staff who saw that happen.
Since media interest was present at the exits of the estate for a good period following hte funeral any possible movement of a coffin could not have gone unnoticed. The church at Gt Brington is very close to the estate, very small, and the whole village would easily have known that the sealed underground Spencer family vault had been disturbed.
If we back track further - there are those who say she was "secretly cremated" (in the family oven, or on a bonfire, maybe...
) and her ashes added to the vault - same thing, it would need opening & resealing...
We have witnesses who visited her lying at rest in London up to the evening prior to the funeral, in buildings surrounded permanently by thousands of mourning public, so she was still there until the funeral left. The coffin was carried by soldiers, one of whom was the nephew of a friend of mine, who assures me they were not carrying an empty coffin. From the Abbey, the world watched every inch of the way of the drive to Althorp.
If anyone suggests Diana was not present in the coffin at her own funeral you're also asking us to believe that her young sons were either deceived that she was there or complicit in a cover up - neither of which I find credible.
I believe she IS buried on the island and I believe too that she will remain there AND that it is the best place for her possibly to be.
