Vodafone looks set to win approval for its €7.2 billion acquisition of Spanish cable operator Ono.

Sources cited by Reuters on Thursday claimed that European Union antitrust regulators have no concerns about the deal's potential impact on competition.

"There are no issues, the deal will be cleared by the European Commission without conditions," said one of the sources, in the report.

The Commission is due to announce its decision on 2 July.

Vodafone has been busy bulking up its fixed-line assets across Europe and Spain is no exception.

When it agreed to acquire Ono in March, the U.K.-based mobile giant was already preparing to launch fibre-to-the-home (FTTH) services in Spain using the network it rolled out in partnership with rival operator Orange.

EU competition regulators have paid close attention to in-country consolidation between telecom service providers, particularly deals involving two fixed broadband operators or two mobile operators.

However, EU authorities have generally acted with more leniency toward mergers between fixed and mobile operators, as evidenced by its swift approval of Vodafone's acquisition of Kabel Deutschland last year.

The likelihood of endorsement from Brussels was partly what inspired conglomerate Vivendi to sell its French mobile arm SFR to Altice, parent of local cable provider Numericable. This was despite a higher competing offer from mobile operator Bouygues Telecom.
