Carrefour had no immediate comment.

One reason for postponing the announcement was the intention to maintain good labour relations during the Christmas holidays and thus avoid labour trouble, BFM said.

"All points to January," it said.

Alexandre Bompard, who joined as CEO in July, is working on plans to try to revitalise Carrefour, the world's second-largest retailer, which warned in August its operating profit this year could fall by around 12 percent.

By 0739 GMT, Carrefour shares were down 2.17 percent at 17.14 euros, among top decliners on the CAC-40 index of French blue chips <.FCHI>
