The late Princess of Wales' ex-chef Darren McGrady has hit out at Earl Charles Spencer insisting he wasn't "there for her" before she died in 1997 aged 36, after her sibling revealed this week he wished he could have "protected her".

Darren retweeted an article about Charles' comments on Twitter and added: "This makes me want to throw up! Where were you when she needed you ? #PrincessDiana #dianainherownwords

"NO! Not going to sit her and be quiet while little brother tries to rewrite history. You WEREN'T THERE FOR HER ! (sic)"

Dickie Arbiter, Queen Elizabeth's former press secretary, who also worked closely with Diana, responded to Darren's tweet, insisting Charles was being a "hypocrite".

He tweeted: "Such hypocrisy from Charles Spencer. He forgets some of us were there when he turned his back on Diana (sic)"

The pair are believed to be referring to an incident in April 1996 when Diana wanted a home on the Althorp estate, Earl Spencer's home, to use at the weekends aside from her Kensington Palace apartment following her divorce from Prince Charles.

Her former butler Paul Burrell previously revealed a note sent to Diana by Earl Spencer refusing her permission to live at Althorp, Northamptonshire, and the ex-footman said it left her in tears.

The note read: "I'm sorry, but I've decided that the Garden House isn't a possible move now. There are many reasons, most of which include the police and press interference which would inevitably follow.

"I know you will be disappointed but I know I am doing the right thing for my wife and children. I am just sorry I cannot help my sister!

"I fear for you. I know how manipulation and deceit are parts of the illness ... I pray that you are getting appropriate and sympathetic treatment for your mental problems.

"After years of neglect on both sides our relationship is the weakest I have with any of my sisters ... perhaps you have more time to notice that we seldom speak."

But he did offer her some other alternatives.

He wrote: "In theory it would be lovely to help you out and I am sorry I can't do that ... If you are really interested in renting a farmhouse, either here or in Warwickshire or Norfolk, that would be wonderful."

Charles insisted this week he always felt "intensely protective" of his sibling.

Speaking on US documentary 'The Story of Diana' on ABC, which will be broadcast this week, he said: "What could I have done? But you always think, 'God, I wish I could have protected her.' It was devastating. I always felt ... intensely protective towards her."
