JERUSALEM, June 29 — Israel’s disgraced president, Moshe Katsav, submitted his resignation to parliament this morning amid fierce public criticism after the state agreed to drop rape charges against him in exchange for an admission of guilt for lesser offenses.

Mr. Katsav’s resignation, one of the terms of the agreement, is to go into effect on Monday. Once out of office, he will be charged with committing an indecent act without consent, sexual harassment of two women and harassing a witness, the attorney general, Menachem Mazuz, announced on Thursday.

Under the shadow of the investigation, Mr. Katsav took a leave of absence from his presidential duties, which are largely ceremonial, in January; his seven-year presidential term was due to end on July 14.

In a curt letter sent to Parliament Speaker Dalia Itzik by courier, the contents of which were published in the Israeli media, Mr. Katsav made no reference to the reasons for his resignation and did not express any remorse. He only stated his request to move up the end of his term by two weeks and announced his resignation.
