Prince Harry's memoir caused irreparable damage to his relationship with Prince William and Kate.

Mere mentions of Kate in the memoir caused explosive fights behind Palace doors.

Kate felt William should have defended her more.

The Palace initially thought saying nothing was best.

The admissions come as no shock following previous revelations by author Tom Quinn.

The Cambridges have had terrible rows where they throw things at each other.

William and Kate are constantly surrounded by palace aides.

Their stress level is high because of the constant presence of palace aides.

The situation is likened to a Jane Austen novel.
