Ms Haynes told the Herald: "Everyone is going to be popping in to do their bit. Tomorrow could be very entertaining to watch. There are parts that are owned by different people - even now I know that Linda will come in to read the statement about her lost political career as she sought justice." Haynes, who was extradited from Britain in February 2017, decided at the last minute to plead guilty to the charges of rape, buggery and indecent assault against his daughter in Sydney in the 1970s and 1980s.

Ms Haynes went on: "Lots of alters that most people haven't met will be rocking up tomorrow to tell their stories through their victim-impact statements. It's the only way to do it. Dad needs to confront the enormity of what he did - and the enormity of what he did is 2500 alters. To just let Jeni or Linda read that statement is a cheat. He needs not just to hear it but to actually see it in front of him. This is what he did to me.

"I hope he struggles with it. I imagine it is probably going to be the most emotional day of my life. I anticipate that I will come out of it feeling quite wrung out, but I think tomorrow is going to be the beginning of my brand new life." Richard Haynes with Jeni and her siblings. Ms Haynes writes in the victim-impact statement: "The impact of my dad’s offending has had far-reaching effects and the ramifications have destroyed my life. He has sent a wrecking ball through my hopes and my dreams. "He chose to plead guilty finally not because he was struck by the enormity of his acts but, rather, because he could not handle Symphony telling what he did to her in excruciating and explicit detail." "My dad forced me to develop multiple personalities as the only way I could cope with his abuse. Dad’s abuse was extreme, violent, sadistic, unescapable, unavoidable, constant and life-threatening, not to mention overwhelming.

Jeni Haynes aged 4 at the family home in Bexleyheath, London, before the family moved to Australia. "Jeni would not have survived the abuse and the day-to-day consequences of the abuse without Symphony and her highly creative strategy. But Symphony is deeply traumatised, hurt, damaged and devastated as a result. As are all the other alter personalities who have done their jobs so well and kept Jeni alive. Without MPD I would be dead. This may sound melodramatic, but it is quite simply the truth." She states the abuse destroyed her childhood, ruined her educational prospects and devastated her employability with immense economic cost as she was forced to live on a government benefit. "My dreams of a political career have been unfulfilled as a direct result of seeking justice for the abuse I suffered. I have had to choose between justice and a political career. "As the vast majority of counsellors are not able to deal with the level of trauma I have experienced, I have been forced to seek therapy from a psychiatrist.
