A young French author formally accused Dominique Strauss-Kahn of attempted rape on Tuesday and broke her long public silence with a dramatic account of fending off an attacker who ripped at her clothes as they fought on his apartment floor. Tristane Banon\'s criminal complaint was already spawning an ugly public battle that appeared to be dividing France, and follows trans-Atlantic mudslinging over the Guinean maid who accused Strauss-Kahn of forcing her to perform oral sex in his New York hotel room. The sudden weakening of the chambermaid\'s case by New York prosecutors\' doubts about her credibility revived hopes in Strauss-Kahn\'s Socialist Party that he could make a triumphant return to France and retake his position as the strongest challenger to conservative President Nicolas Sarkozy in the 2012 election. Those hopes could be undermined by the 31-year-old writer\'s legal action, which is expected to set off a lengthy preliminary investigation by prosecutors into whether there is enough evidence to pursue a case in France.

Polls already have found French voters evenly divided over whether they want Strauss-Kahn to return, with women more likely to object to his reviving a political career. A poll of 860 people conducted over the weekend by the magazine Nouvel Observateur found that 54 per cent didn\'t want Strauss-Kahn to run in the October Socialist Party primary, and 63 percent didn\'t believe that he would end up running. \"He grabbed my hand, then my arm, I told him to let me go and that\'s when the fight started. He pulled me towards him, we fell down and fought on the ground for a few minutes,\" Banon told news magazine L\'Express. She said she started kicking him with her boots, then finally broke free, ran down the stairs and called her mother from her car. \"I couldn\'t even drive I was trembling so much,\" she said. The Associated Press does not name alleged victims of sexual crimes unless, like Banon, they choose to publicly identify themselves. Many of Strauss-Kahn\'s allies took to the airwaves Tuesday in attempts to undermine Banon and question the timing of her complaint about an incident that she says took place in 2003, when she was attempting to interview Strauss-Kahn for a book project. Banon first recounted the incident on a 2007 television show, in which Strauss-Kahn\'s name was edited out. Her lawyer began discussing the possibility of bringing charges after Strauss-Kahn\'s May 14 arrest, but Banon still said very little. \"Tristane Banon has been telling her story for months and years. She\'s filing her complaint today,\" Socialist lawmaker Jean-Marie Le Guen told reporters. \"In that, I see a certain opportunism that I associate with this mudslinging, these disinformation campaigns against Dominique Strauss-Kahn at the moment when American justice is about to acknowledge his innocence.\" Strauss-Kahn\'s lawyers on Monday labeled Banon\'s account \"imaginary\" and said they would file a criminal complaint of slander against her. Banon told French news magazine L\'Express that she was tired of hearing \"lies and rumors\" told about the incident. \"I can\'t take it anymore hearing that I must be lying because I haven\'t filed suit,\" Banon said. Strauss-Kahn is free on bail in New York, charged with attempted rape and other crimes. In a further twist to the saga Tuesday, his New York accuser filed a libel suit against the New York Post after it called her a prostitute. Banon said she had waited eight years before filing her complaint because \"it\'s very difficult for any woman in this situation ... and it\'s even more difficult when you know in advance that it\'s doomed to failure.\" Banon says she described some of the attack in an \"autobiographical novel\" she published in 2006 called The Trapezist. \"I left out some sordid details, about his fingers in my mouth, his hands in my underwear after he ripped off my jeans and my bra,\" Banon said. Lawyer David Koubbi said Banon had been dissuaded from filing charges after the incident by her mother, Anne Mansouret, a regional councilor in Strauss-Kahn\'s Socialist party. Mansouret now says she regrets urging her daughter not to file a complaint after the incident but she feared that taking action against such a powerful Frenchman would affect her daughter\'s career. Mansouret told the French radio station RTL that her daughter Tristane Banon \"considers the only way to end this is in fact to file a complaint, to say that at least justice can be done.\" \"She\'s a young woman who\'s matured,\" Mansouret told RTL. \"She took this decision, I suppose, after maturely reflecting.\" Mansouret said she thought that by filing the complaint, it would help her daughter \"rebuild herself.\" \"She tried to move ahead without doing that, and it wasn\'t possible. She arrived at a level of suffering. It\'s suffering to be permanently harassed by people who criticise how you\'ve acted,\" Mansouret said. If Banon\'s complaint leads to preliminary charges, there will then be a lengthier investigation, sometimes lasting years, to determine if the case should go to trial before a judge. The same process would apply to the slander complaint against Banon. A slander charge can be brought against anyone who French prosecutors believe deliberately filed a false complaint with authorities. In Banon\'s case, an investigation would begin only if her attempted rape complaint is found to be false. A slander charge carries a maximum term of five years in a prison and a 45,000-euro ($65,000) fine. French prosecutors could decide not to pursue the case against Strauss-Kahn if they find evidence he engaged in forcible sexual contact that fell short of attempted rape. The statute of limitations on sexual assault charges in France is three years, while attempted rape charges can be filed for up to 10 years after the alleged crime. Strauss-Kahn has relinquished his passport to authorities in New York and his next court appearance is on July 18.
