Unilever PLC (LSE:ULVR) is splitting off its highly political Ben & Jerry's ice cream business from the rest of its food brands in a move that experts said could make it easier to pursue a sale. The company will divide its food business in two, with ice cream, which also includes Magnum and Solero, to be separated from its nutrition unit, which will house brands such as Marmite, Hellmann's mayonnaise and Knorr stock cubes.
