Italy's antitrust agency said on Wednesday it had fined Unilever's Italian unit more than €60 million ($102m) for abusing its dominant position in the country's ice cream market.
It said Unilever had abused its position in single-wrapped so-called impulse ice creams, intended for immediate consumption, which it sells through its "Algida" brand.
The local unit of the world's biggest ice cream maker said in a statement it rejected the agency's conclusion and would appeal, according to the Daily Telegraph.
Italian authorities started the probe in 2013 when a small producer of organic fruit lollies called La Bomba accused Unilever of forcing local retailers not to sell its popsicles.
La Bomba, based in the seaside town of Rimini, said Unilever had struck deals with operators of beach resort, bars and campsites to exclusively sell the bigger firm's ice creams.
