As Chris Huhne's legal team fought to get his case thrown out, his fractured relationship with his son Peter was revealed in a series of text messages read out to the court.
The messages, revealed for the first time today, showed distraught Peter Huhne's anger at his father about the break up of his parents' 26-year marriage.
The messages between Peter, then 18, and his father started in June 2010 when he told him: ''I don't want to speak to you, you disgust me''.
In a series of texts revealed to the court, Huhne repeatedly contacted his son, telling him he loved him and wanted to speak to him, but the teenager rebuffed his attempts, sparing no words in telling his father what he thought of him.
After a letter from the politician in June 2010, the 18-year-old shot back: ''So nice to see our entire relationship reduced to lies and pleasantries in that letter. Do you take me for an idiot?''
The following month, on July 30, Huhne told his son: ''I understand that I have really offended you but I hope that the passage of time will provide some perspective... I love you and I will be there to support you if you ever need it.''
But the plea fell on deaf ears as his son replied: ''You are right - the perspective involves me getting angrier with every day that goes by. You just don't get it.''
Huhne tried again on Christmas Day in 2010, wishing his son happy Christmas and saying he loved him, but again was told in no uncertain terms to leave him alone.
The former energy secretary maintained a keen interest in Peter's education, asking him that same month if he had heard from an Oxford University college.
He later congratulated him, telling his son he was proud, but his praise was dismissed as his child told him he had ''no right to be proud''.
As the year turned, Huhne's interests in his son's education continued as he told him on February 27: ''Saw a Beckett reference and thought of you in Godot, MI6 used to be full of people who did languages at Oxford. Love you.''
Again in May 2011, after allegations about him and Pryce emerged, Huhne wished his son the best in his exams, telling him: ''I do hope your exams are going okay, despite everything over the last few weeks. Thinking of you, love you, Dad. PS It's granddad's birthday today.''
It was later that month that the conversations were to come to a head, as Peter Huhne urged his father - who was protesting his innocence - to own up.
On May 21, a few days before Huhne and Pryce were to be interviewed by police, he texted his father: ''We all know that you were driving and you put pressure on mum. Accept it or face the consequences. You've told me that was the case. Or will this be another lie?''
Huhne declared the matter was something he would have to discuss with his mother.
The distraught teenager replied: ''It's not about her its about your accepting responsibility to me.''
