LONDON -- Vodafone, one of the world's largest telecommunications company, agreed Monday to buy Spain's Ono for 7.2 billion euros ($10 billion) as it seeks to expand operations in its primary European market.

Grupo Corporativo Ono S.A. provides phone, mobile and television services to 1.9 million customers and has the largest "next-generation network" in Spain, reaching 7.2 million homes, or 41 per cent of the country. Vodafone says Ono has abundant spare capacity, giving it space to expand.

"Demand for unified communications products and services has increased significantly over the last few years in Spain, and this transaction - together with our fiber-to-the-home build program - will accelerate our ability to offer best-in-class propositions in the Spanish market," Vodafone Chief Executive Vittorio Colao said in a statement.

Vodafone is flush with cash after agreeing last year to sell its stake in a U.S. venture to Verizon for $130 billion in cash and stock -- one of the biggest deals in corporate history.

Monday's deal marks Vodafone's second major acquisition in Europe, after its purchase of Kabel Deutschland last year. Vodafone was attracted by Kabel Deutschland's extensive cable network, which it could use to expand its fixed-line, broadband and television business.

The deal allows Vodafone to accelerate its expansion in Europe, and to take advantage of the rapid increase in the adoption of unified communications products and services in the Spanish market. Ono has invested approximately 7 billion euros in its network since 1998.
