Bowing to pressure from the European Commission, hotel-room booking site Booking.com has agreed to change the way it presents offers, discounts and prices.

Consumer associations had complained that information on the site was misleading.

"All companies must meet our high consumer law standards if they want to do business in the EU," Didier Reynders, the European Commissioner for Justice and Consumers, said in a statement. "As a market leader, it is vital that companies like Booking.com meet their responsibilities in this area, ensuring that online accommodation reservation systems are free from manipulative techniques such as hiding sponsoring in ranking, unduly putting time pressure on users or misrepresenting rebates."
