UK-based mobile phone network leviathan Vodafone is in talks to merge its Greek telecoms business with privately-owned rival, Wind Hellas.Discussions with Largo Limited, the owners of Wind Hellas, are at an early stage and there is no certainty as to whether an agreement will be reached, the Vodafone statement said.A merger of the two companies' interests in Greece would create a stronger rival to the leader in the Greek market, Cosmote. Vodafone is the second largest mobile phone network operator in Greece, while Wind Hellas is the third largest.A spokesman for Vodafone was quoted in the British financial press on Monday as saying that media reports that the group is discussing a cash offer for Wind Hellas are not correct.--jh
