Jacintha Saldanha took her own life after she was duped into giving up information about Prince William's wife, Catherine, to two Australian Djs, who fooled her into thinking they were the Queen and Prince Charles live on air.
The stunned radio hosts have since stepped down from their show following the tragedy, and now the former The Smiths frontman is calling on the royals to show some remorse.
He tells New Zealand's 3News, "Even with the recent story about the nurse killing herself in King Edward Hospital, there's no blame placed on Kate Middleton (Catherine), who was in the hospital as far as I could see for absolutely no reason.
"She feels no shame about the death of this woman, she's saying nothing about the death of this poor woman. The arrogance of the British royals is staggering, absolutely staggering. And why it's allowed to be I really don't know."
The Duchess checked into the hospital earlier this month (Nov12) with severe morning sickness - but Morrissey is convinced the visit was unnecessary.
He adds, "Does she have a health condition...? What is the health condition? I mean morning sickness already? So much hoo haw and then suddenly as bright as a button as soon as this poor woman dies she's out of hospital? It doesn't ring true.
"And I'm sure the Palace and Clarence House (Princess of Wales' residence) put maximum pressure on this poor receptionist and nurse, and of course that's kept away from the press. I'm sure the British press hounded this poor woman to her death, that's kept away. And by this time next week she'll be forgotten. And that's how the British royals work."
