Former Home Secretary Charles Clarke has described how he faced false rumours he was having an affair with his former special aide at the Old Bailey phone hacking trial.
He told jurors he had threatened to sue the Sun for libel if it ran such a story.
Prosecutors allege that journalists at the News of the World (NotW) accessed Miss Pawlby's voicemails in 2005 after hearing a rumour that the pair were having an affair.
Jurors were shown an email sent by journalists from the NotW features desk, which said:
Lewis (Panther - a journalist) has had a tip that Home Secretary Charles Clarke is having an affair with his blonde, attractive special adviser Hannah Pawlby.
He got this from a Westminster insider who fancied Pawlby, was going to ask her out and was told 'Don't bother wasting your time, she's with Charles'."
The-then features editor, Jules Stenson, replied to colleagues saying that the story was a "non-runner" because the news team had "a head start".
Andy Coulson was told about a recording of a voicemail from actress Sienna Miller on actor Daniel Craig's phone, his trial has heard.
Jude Law discovered for the first time today that a relative had allegedly been paid by a newspaper for information.
A former tabloid reporter has revealed to the phone-hacking trial how the "dark arts" were used by newspapers to secure stories.
