Orange Spain is reported to have lodged a complaint with the country’s competition regulator over a partnership between market leader Telefonica and new entrant Yoigo.

Under the terms of a deal announced earlier this year, Telefonica will be able to access Yoigo’s LTE network as it rolls out its own 4G infrastructure, while Yoigo will be able to resell fixed voice and broadband services from Telefonica in order to offer customers bundled packages.

According to Reuters, Orange has complained that the deal removes Yoigo as a competitor and turns it into an “offshoot of Telefonica”, enabling the former monopoly to gain more market share in fixed line services.

The move is not a surprise: when the deal was first announced, Orange was reported to have contacted the competition regulators about its concerns.

Telefonica and Yoigo previously said that they intend implementing their partnership from the last quarter of this year.
