PARIS — Chanel will not renew a contract with Kate Moss that expires in October, but a spokeswoman said Wednesday it had nothing to do with recent publicity about the supermodel's cocaine use.

"Kate Moss has a contract until the end of October,'' said Julie Le Blevec, spokeswoman for Chanel perfumes. She added, "We are not planning to stop the advertisements before then.''

Moss has been the face of Chanel's Coco Mademoiselle perfume since 2002.

"The contract was always going to end in October,'' Le Blevec said.

She denied media reports that Chanel was dropping Moss and said the decision was not based on the model's recent acknowledgment of using drugs.

"It's not about renewing the contract or not. The contract finishes at the end of October and we don't have any projects with her,'' Le Blevec said.

H&M, Europe's largest fashion retailer, said Tuesday it would drop a planned advertising campaign with the 31-year-old model after she acknowledged recently using cocaine.

Recent pictures published in Britain's Daily Mirror appeared to show Moss snorting cocaine, prompting London police Wednesday to say they were investigating the allegations.

Any decision about charges, London's police chief said, should take account of the impact of the case on young people.

Sir Ian Blair, the commissioner of the Metropolitan Police, told reporters that he had been involved in the decision to investigate Moss.

He said he didn't wish to comment directly on the case, but added: "We have to look at the impact of this kind of behaviour on impressionable young people and if there is evidence, something should be done about it.

London's police generally investigate drug dealers rather than users, but that policy is "adaptable to the impact of events,'' Blair said.
