Former IMF chief Dominique Strauss-Kahn pleaded not guilty on Monday to charges he sexually assaulted a New York hotel maid in a case that cost him his job and a chance at the French presidency.

Strauss-Kahn, 62, faces up to 25 years in prison if convicted on charges including attempted rape, sex abuse, a criminal sex act, unlawful imprisonment and forcible touching.

His lawyer, Benjamin Brafman, told Reuters he will plead not guilty in New York Supreme Court before Judge Michael Obus.

Praised for his role tackling the 2007-09 global financial crisis and attempts to keep Europe's debt crisis under control, Strauss-Kahn resigned as IMF managing director a few days after his May 14 arrest in the first-class section of an Air France plane, minutes before it was to depart New York for Paris.

He was accused of attacking a 32-year-old African immigrant a few hours earlier when she came to clean his suite at the luxury Sofitel hotel in Midtown Manhattan, apparently believing it had been vacated.

Strauss-Kahn, who has four daughters, spent four days in New York's Rikers Island jail before he was released on $1 million cash bail and $5 million bond and placed under house arrest with 24-hour armed guards and electronic monitoring.

He spent a few days in a Lower Manhattan apartment but is now living in a luxurious townhouse rented by his wife -- French television journalist Anne Sinclair -- in Manhattan's TriBeCa district. The townhouse has a gym and home cinema and was last posted for sale for almost $14 million.

A prosecutor estimated Strauss-Kahn would pay $200,000 a month for his security arrangements.

Strauss-Kahn's lawyer has said that although his client has a net worth of roughly $2 million, his wife, an heiress, has "substantially greater assets". So far, Sinclair has not displayed any hesitation about using her personal wealth to help her husband.  - Reuters
