DIANA & HER FAVORITE CHARLES

THEY were always very close because they were the two youngest left at home when the two eldest left the nest.
Like all siblings they had their moments but in the twlilight of Diana's short life her only brother was her rock. She named him in her will, along with her mother as guardian for her children even though she knew the Windsors wouldn't honor her wishes. What mattered was that her wishes were open and expressed formally.

True enough that one parent survived her death but she expected her mother to be consulted by their father and in the event of her mother's death, it was down to Charles Spencer to share in decisions and consultations.

Behind the scenes this wish has been carried out by the two lads on their own. Both William and Harry turn to Uncle Spencer from time to time for advise. The Telegraph reported Harry consulting the earl over personal relationships. They are all three old Etonians.

It is of note that Diana spent her last birthday shortly before her death with her brother and that she spoke with him via telephone during the time she was in Paris.

When first I saw this poignant photograph it made me think of how she and Harry may have appeared in a picture together had she lived to see him reach that age.
