PARIS — A junior government minister resigned Sunday after two women filed sexual harassment suits against him last week, becoming the first clear political casualty here of the fallout from the arrest of the French economist Dominique Strauss-Kahn.

Prime Minister François Fillon confirmed that he and President Nicolas Sarkozy had accepted the resignation of the official, Georges Tron, as the state secretary for civil service.

The two women, ages 34 and 36, have accused Mr. Tron, 53, of repeated sexual assaults from 2007 to 2010 when they worked for him at City Hall in Draveil, near Paris, where he is mayor. The plaintiffs have said they were emboldened by the example of the New York City hotel maid who accused Mr. Strauss-Kahn of sexual assault.

Mr. Strauss-Kahn was arrested on May 14 and resigned as managing director of the International Monetary Fund.
