Georgia Beesley said her mother, Vicky Pryce, told her that Chris Huhne had nominated his then-wife as the driver without telling her, and when it arrived, she was already named as the driver.
"I know she felt pressured into signing the form," she said.
Mrs Beesley said the issue resurfaced as Huhne lost his licence soon afterwards when he was caught talking on his mobile phone, telling Southwark Crown Court:
He lost his licence anyway that summer and mum had to drive him whenever he needed driving. A lot of comments were made around that time, 'I have got to drive you anyway, even though I took the points'. There was quite a bit of resentment.
She said her mother was "very upset she had had to do something she really didn't want to do and the outcome was exactly the same".
Vicky Pryce said she was "not proud" of herself after the Sunday Times splashed the story of her revelations on her husband's speeding points, and said she was very personally vulnerable at the time, and possibly irrational.
She said she went to the press because she wanted the story explained in the "right way."
If I had wanted to ruin my husband at the time I could have thought of lots of other things to expose publicly.
2010 was a very difficult circumstance when the family had really been torn apart and where the person they were relying on, who was me, was actually very fragile.
I am not proud of what happened. Now of course I would never ever have gone down that road. I did not perhaps behave rationally, there's no doubt about that.
It was a very, very tough time for me and also for the rest of my family and I did things which I am not proud of.
