Sex-obsessed former IMF chief Domninique Strauss-Kahn was 'treated like the Messiah' when he arrived at orgies, a prostitute who took part in his group sex sessions has revealed.

The vice girl, named Jade, praised the shamed 62-year-old economist for his 'courtesy and respect' during the sleazy swingers' parties.

The Belgian hooker also told how she had sex with Strauss-Kahn on the night before he was arrested for trying to rape a New York hotel chambermaid on May 14.

And she said the world's former top banker even invited her to his offices at the headquearters of the International Monetary Fund in Washington DC.

Her claims come after Strauss-Kahn confessed to taking part in orgies, but said he never realised any of the female participants were being paid for sex.

Jade, 29, spoke of Strauss-Kahn's love of orgies in a lurid interview today with French newspaper Nord-Eclair.

And she agreed that the man once tipped as the next president of France may not have known he was having sex with call girls.

She said: 'Most of the people at these evenings would have probably thought the participants were all just consenting adults.

'I must say, I found DSK to be very pleasant and overly polite.

'Each encounter with him was mutually respectful. I have always ensured I am seen as a woman and not an object. When people respect each other, nothing bad happens.'

She spoke of the atmosphere at one orgy that was 'packed with well-known people' at Paris's four-star Murano Hotel, as they waited for DSK to arrive.

She added: 'Everyone was saying, "He's on his way". I asked who they meant, as I had not heard of him at the time.

'They all seemed to be waiting for Dominique like the arrival of the Messiah.

'When he turned up, everyone was as usual very admiring of him. He always had a certain charisma about him, an aura. Although at that session I had very little contact with him.'

Another prostitute named Florence said she took part in 11 orgies over six years with the former banker.

The 30-year-old added: 'At these evenings, DSK had sex with every girl in the room.

'I'm not saying he raped me, but I got the feeling that he liked rough sex.'

Strauss-Kahn has been engulfed in a tide of sex scandals since being acccused of attempting to rape U.S. chambermaid Nafissatou Diallo in May.

The charges were eventually dropped and he returned to France, where he escaped more accusations of trying to rape writer Tristan Banon eight years ago.

Those accusations were also dropped, but he was then named as the client of a sprawling vice network operating out of a five-star hotel in Lille, northern France.

He has admitted to having an 'uninhibited but legal sex life' but said he never paid for sex and had 'a horror of prostitutes and pimps'.

He has demanded to be interviewed to clear his name of malicious insinuation' that he paid hookers for sex.

It also emerged this week that Strauss-Kahn was quizzed by police five years ago in a Paris park notorious as a haunt for transvestite prostitutes.

French interior minister Claude Gueant made the revelation to a French Sunday newspaper.

Stauss-Kahn later admitted that he had been stopped, but said he was with his wife Anne Sinclair at the time, and it was a routine check that only happened because they lived nearby.

Strauss-Kahn's allies have claimed that government agents were behind a phone-hacking 'plot' to wreck his political career by having him falsely accused of attempted rape.

Mr Gueant - a staunch ally of President Sarkozy - has branded the allegations as 'ridiculous' and said he is 'sick and tired' of conspiracy theories.
