(Telecompaper) The Virgin Group has expressed an interest in acquiring TeliaSonera's Spanish subsidiary Yoigo, according to unnamed sources cited in business daily El Economista. The negotiations are being led by Juan Villalonga, former chairman and CEO of Telefonica, who now acts as business advisor to Virgin Mobile Latin America (VMLA) and is co-founder of the investment fund Emergent Telecom Ventures. Yoigo declined to comment on Virgin's potential interest in the company, which is currently Spain's fourth mobile network operator with a share of just over 6 percent of total service revenues. When TeliaSonera sought to dispose of its Yoigo stake in 2012, it failed to attract bids matching its EUR 1 billion valuation from interested companies such as Vodafone and Orange.
