A politician in France has called on retailers and restaurants in the country to stop offering Californian wines to their customers.

The call to arms follows California's ban on the production and consumption of foie gras in the state from 1 July. A law passed in the US state in 2004 declared that the act of gavage - the force feeding of corn to geese and ducks - was harmful to the animals' well-being.

It gave breeders seven years to find an alternative production method.

Philippe Martin, the head of the Gers Council in south-west France, the heart of foie gras-producing country, said that his proposed ban on Californian wines should last until the state withdraws the law prohibiting the producer.
