A French appeals court on Monday ordered doctors to resume giving food and water to a French quadriplegic, lawyers said, some 12 hours after medics switched off the man's life support against his parents' will.

The fate of Vincent Lambert has renewed a fierce debate over the right to die that has split his family and the country.

"The feeding and hydration of Vincent must be restarted without delay," declared Jean Paillot, a lawyer for Lambert's parents who launched multiple legal bids to keep his care going. "It's a huge victory, and only the first."
