Dominique Strauss-Kahn was acquitted of sex crime accusations by a French court yesterday, the final chapter in a transatlantic scandal that destroyed the political ambitions of a man once tipped to become his country’s president.

A court in the northern city of Lille dismissed charges that the former International Monetary Fund chief’s sexual escapades with prostitutes amounted to “aggravated pimping” – the charge on which French magistrates sent him to trial.

The verdict came four years after sex assault accusations by a New York hotel maid ended his political ambitions and forced him to step down as head of the Washington-based IMF and ends Strauss-Kahn’s legal battle on both sides of the Atlantic. But local media said the damage to his reputation after four years of occasionally salacious revelations about his sexual practices almost certainly ruled out a political comeback.

He argued that he was a libertine with an appetite for rough sex

Having settled financially with Sofitel maid Nafissatou Diallo after New York prosecutors abandoned criminal charges in 2011, the 66-year-old stood accused in France of instigating the organisation of orgies with prostitutes. “He cannot be attributed the role of instigator,” judge Bernard Lemaire said when reading out a verdict in the presence of Strauss-Kahn and 13 others. “He just availed of the sexual services of a group.”

Strauss-Kahn and his lawyers had argued that he was a “libertine” with an appetite for rough sex but was unaware that women he frolicked with at parties and hotels in Paris, Lille and Washington, mostly while in the IMF post, were prostitutes.

Since returning to Paris after his IMF stint in Washington abruptly ended, Strauss-Kahn has sought to start a new life with a now-troubled venture in investment banking and a new female partner, after celebrity journalist wife Anne Sinclair left him.

In the so-called Carlton affair, named after a luxury hotel in Lille, the acclaimed economist and French finance minister of the late 1990s was tried with 13 others on charges that he instigated sex parties with prostitutes. He flatly denied any wrongdoing. While frequenting prostitutes is not a crime in France, procuring them is. A conviction on charges of “aggravated pimping” can carry a sentence of up to a decade in prison and a fine of up to €1.5 million.

The Lille ruling closed a saga that began live on TV when Strauss-Kahn was shown walking handcuffed through New York streets after police escorted him off a plane about to leave for Europe.

The affair felled one of the world’s most powerful financial policymakers days before he planned to announce his candidacy in France’s 2012 presidential election.

“DSK”, as he is known to many French, was runaway favourite in opinion polls at the time.

Instead, Francois Hollande ran as the Socialist candidate and beat conservative incumbent Nicolas Sarkozy. Strauss-Kahn has since set up his own business consultancy firm but talk of a political comeback fizzled out long ago. He has made appearances at banking conferences as a paid guest speaker and took part in an investment venture with a partner who committed suicide.

Anne Sinclair, the ultra-wealthy heiress to an art dealer family’s assets, split from Strauss-Kahn after their return to Paris .

Ivan Levai, Sinclair’s partner before she met Strauss-Kahn, told BFM TV yesterday acquittal would allow the former French finance minister open a new chapter in his life but that he was politically ruined.
