Dominique de Villepin, France's prime minister, will next week stand in for an ailing President Jacques Chirac at the United Nations' meeting in New York, the venue where he won the admiration of the French public and the animosity of the US administration for his passionate opposition to the Iraq war.

Mr Chirac, 72, was yesterday released from hospital a week after being admitted with a vascular complaint. Doctors told the French president he should be "reasonable" and refrain from air travel for six weeks. However, Mr Chirac did not reveal any further details about his medical condition in spite of criticism that he has been excessively secretive about his health.
