Of course the hospital is going to say that they didn't punish her or discipline her in any way. I find that hard to believe. They are one of the top hospitals in the UK and are known specifically for their high security. For this to happen to the royal family made THEM look bad and I find it very hard to believe that the employees involved were not at least come down on very hard by upper management. And also, it was my understanding that this was just the nurse that initially transferred the call, NOT the nurse that gave out info.
I do also agree with PP that said that this girl must have had other things going on in her life. I certainly hope an otherwise happy person wouldn't kill themselves over something like this.
