Antitrust prosecutors advising the Belgian competition watchdog, the Belgian Competition Council (BCC), have told the regulator that incumbent fixed line and broadband provider Belgacom has abused its dominant position in the country’s fixed line sector, Reuters reports. It is understood that the prosecutors have claimed that Belgacom has actively engaged in a margin squeeze designed to limit competition. The investigation stems from a complaint filed by alternative operator Tele2; the altco has argued that the incumbent’s high wholesale charges combined with its own low-cost retail offering, Happy Time, which was launched in 2005, hindered other operators from achieving decent profit margins. The BCC will now consider the matter further, and is expected to issue a final ruling on whether it considers there was an infringement of competition law. Belgacom has refuted the claims, and will fight the charges.
