During 2 hours in the witness box, Pryce painted a picture of Huhne as a hard-working and ruthlessly ambitious politician who thought he had few intellectual peers.
"I don't think there are a lot of people who he believes are his superiors," she told the court. "In fact, I can't think of anyone, intellectually."
She told how he put his ambitions ahead of his family as he sought to climb the political ladder.
Pryce, a talented and highly successful economist, claimed that her former husband believed he was "above the law" and bullied her into taking three points for her licence.
Pryce "exploded" when she learned that he had sent in a form nominating her as the person who was driving, but felt she had no choice but to sign up to the pact after he stood over her as she signed a police notice, she told the jury of eight women and four men.
Southwark Crown Court heard that in 2003 she told one of her Clapham neighbours, Constance Briscoe, a lawyer and part-time judge, about Huhne passing the points to her in that year.
But she only came forward and revealed his crime more than seven years later after the break-up of their 26-year marriage, when his affair with an aide, Carina Trimingham, was exposed in June 2010.
His confession came weeks after he was re-elected MP to Eastleigh after using campaign leaflets that showed their wedding picture and included the comment: "Family matters to me so much. Where would we be without it?"
