British pop-star Paul McCartney and Heather Mills

In the saga's latest twist, the Daily Mail quoted an unnamed source close to Mills McCartney saying that the evidence she had was "dynamite".
"She reckons to have tangible evidence showing that Paul not only verbally attacked her but was also physically aggressive.
"As well as charting much of the marriage breakdown on her digital camcorder and having witnesses who will testify to her claims, Heather has another killer piece of evidence in the form of an audio recording," the source said.
Mills McCartney, 38, may also have "some kind of video recording of the pair rowing", the source added.
Documents which emerged earlier this week alleged that, while in Los Angeles in the United States in 2002, McCartney "grabbed her by the neck and pushed her over a coffee table".
They also claimed that McCartney lunged at her with the broken stem of a wine glass which cut her arm and made it bleed.
McCartney, 64, has said in a statement through his lawyers that the only correct place for him to respond to the allegations against him is in the divorce courts.
It was not only the Mail which revisited the story Saturday -- most newspapers devoted numerous column inches and photographs to the latest claims.
The Times reported that Mills McCartney's allegation in the leaked divorce papers that McCartney forced her to stay in bed in the morning was contradicted by a self-help book she wrote while the couple were still together.
In the work, entitled "Life Balance", she wrote that "setting the alarm 30 minutes earlier each morning ... allows me a little bit of personal space before the day begins", the paper said.
Legal experts have warned that the apparent leak could leave former model Mills McCartney with a smaller slice of the singer's estimated 825 million pound (1.21 billion euro, 1.57 billion dollar) fortune.
Elsewhere, the tabloid Sun claimed that McCartney had broken down in tears as he told friends of his fears that he could lose two-year-old daughter Beatrice in a custody battle.
The couple married in 2002 and announced they were separating "with sadness" in May this year.
