There's a podcast available on the 5Live website - www.bbc.co.uk/5live but the synopsis of it is that she talked about how the relationship started, how he behaved when they were together before detailing the type of abuse she suffered. They played the full clip of JLC's rant at her which was much much worse than I'd seen it reported - he goes on to tell her what she'd done wrong, and how she should behave to make it up to him. What was really horrible was that he didn't seem furiously angry with her - angry, but in control of himself.
She said the reason she taped the rant was because she'd already decided to leave him and move back home with her parents. She knew that it would be really hard, so she wanted to have a recording of him of him being abusive so that if she was wavering, she would listen to the recording again and that would stiffen her resolve. At the time of making the recording, she had no intention of going to the Police - I missed the next bit of the interview, so don't know why she decided to.
She said she had been paid for some interviews (but not with the BBC), she wasn't sure how much in total, but she had donated all the money to Refuge to thank them for their support. She also said she was in talks with them about launching a campaign to inform people about abuse. She was fairly scathing about the sentence JLC received, saying a short custodial sentence would have been better, along with some anger management counselling.
Quite hard listening at times, but I thought she came out of it well - you can tell she doesn't fully understand herself why she put up with it now, but she seems determined to show people that his behaviour was abuse, whatever he claims.
