European antitrust officials fined Google a record $2.7 billion for unfairly favouring some of its own services over those of rivals, a report said.

The antitrust decision is related to Google’s online shopping service, which the European Commission said had received preferential treatment compared with those of rivals in specialized search results, reported The New York Times.

Google rebuffed the European Union’s claims on Tuesday, saying that its services had helped the region’s digital economy grow. It has also said that significant online competition remains in Europe, including from companies like Amazon and eBay.

“We respectfully disagree with the conclusions announced today,” Kent Walker, the company’s general counsel, said in a statement. “We will review the commission’s decision in detail as we consider an appeal, and we look forward to continuing to make our case.”
