By Foo Yun Chee and Kate Holton BRUSSELS/LONDON (Reuters) – Vodafone is set to gain unconditional EU approval for its 7.2-billion-euro ($9.79 billion) bid for Spains largest cable operator Ono as regulators do not have competition concerns, three people familiar with the matter said on Wednesday. Buying Ono will enable Vodafone to better compete with Spanish market leader Telefonica. Vodafones 25 percent share of the Spanish mobile market is expected to increase by almost two percentage points after the deal. The people said the European Commission has not demanded concessions from Vodafone, the worlds second-largest mobile operator.
