PARIS — The French justice minister, one of the most outspoken and progressive voices in the government, resigned on Wednesday after a clash over a proposal to strip the citizenship of French-born dual nationals convicted of terrorism.

President François Hollande‘s office said in a statement that he had accepted the resignation of the minister, Christiane Taubira, a native of French Guiana. She had held the position since Mr. Hollande’s election in 2012 and had disagreed with his government on several issues.

The statement said that Mr. Hollande had expressed “gratitude” for Ms. Taubira’s service and that she had reformed the justice system with “conviction, determination and talent.”

At a news conference at the Justice Ministry, she said, “I am leaving the government over a major political disagreement.”
