DS Smith was the top-performing FTSE 100 stock, soaring 10% after revealing it received a preliminary takeover approach from sector peer Mondi.

British American Tobacco added 7.1%, hinting it may sell part or all of its 29% stake in Indian tobacco giant ITC, worth around £14bn. BAT has been working to complete the regulatory process required to give it the flexibility to sell part of its 29% stake. This would allow BAT to release and direct capital to other areas. BAT also achieved an important milestone as its non-cigarette New Categories unit reached profitability ahead of projections.
