The 'Kradbury' takeover saga took a further twist this week when Kraft Foods went hostile in its pursuit of Cadbury - and formally tabled the same bid it first proposed back in September. Unsurprisingly, the Dairy Milk maker immediately rejected the offer and so set in train a series of events that could take both companies into February before a conclusion is reached. Meanwhile, Tesco, which like the rest of the UK's multiples is gearing up for a tough Christmas, was said to have grown its share of the country's grocery market for the first time in two years. Outside the UK, Winn-Dixie, the US retailer, copped some flak from investors, while Mars Inc and Kellogg both revealed challenges in emerging markets.
