Mr Churchill said: “Within a month of Charles and Diana’s wedding, her father Johnnie Spencer said ‘Why don’t you come and have lunch with us at Althorp? I’d love to show you the private apartments.’ So we had lunch, and he said, proud as a little turkey cock, ‘I must show you the guest room that I had completely redone for the return from honeymoon of Charles and Diana.’ He’d had new green silk wallpaper, and the four-poster bed had been completely redone.
“He opened the door and he said, ‘I’m afraid it’s a bit of a shambles now.’
“And clearly there had been a battle royal: there were water stains on the green silk wallpaper; there was a Chippendale chair that was broken; there was a mirror cracked.
“At the time, my wife and I put it down to a lovers’ tiff.
“But now, with the benefits of hindsight, one can see that the marital discord started right at the beginning.
