Reliance Industries, India's largest private sector group, may buy a 13% stake in French retailer Carrefour, the Financial Times has reported, citing an unnamed person familiar with the situation. The 13% stake is owned the Halley family, the French company's largest shareholder. The family is said to be divided about whether or not to sell the shares, which are worth nearly EUR 5 bn. The speculation of new interest comes after French luxury goods billionaire Bernard Arnaut last week purchased 10% of Carrefour in concert with U.S. property fund Colony Capital. Carrefour is the world’s second largest retailer and its large real estate portfolio has been valued at up to EUR 20 bn.
