Princess Diana leaked information about the Prince of Wales to "an ally" in the press in order to "take on" her estranged husband, former News of the World reporter Clive Goodman told the phone hacking trial.
Rebekah Brooks admitted in court she had an affair with her former deputy Andy Coulson, but denied it lasted six years.
She told the Old Bailey the affair was more of a great friendship, part of her "car crash" personal life and consisted of a few "intimate" flings, in 1998, 2004 and finally in 2006.
She said a love note to Coulson, found by police on her computer, was a way of her writing down her feelings to herself and the result of a few classes of wine. She did not send it as she "thought better of it the next day." She said:
"‘First of all, it’s not true. ‘I know that’s what the police and the prosecution say, having analysed the letter.
"Obviously at the time I wrote this, I was in a great deal of emotional anguish, as you can tell from the letter."
The jury has already seen the highly-charged letter. It said:
"The fact is you are my very best friend. I tell you everything, I confide in you, I seek your advice, I love you, care about you, worry about you. We laugh and cry together... in fact without our relationship in my life, I am really not sure how I will cope."
The ex-News of the World chief texted former PM Tony Blair saying she was 'feeling properly terrified' the day before the police interview.
In contrast to yesterday's cool performance, the former editor broke down whilst giving evidence in her phone-hacking trial.
Tony Blair advised Rebekah Brooks how to shield James Murdoch from the fallout of the phone-hacking scandal, the Old Bailey heard today.
