Vodafone CEO Vittorio Colao says the operator is considering an IPO of its Indian unit once the circumstances are right. In an interview with Bloomberg UTV in Mumbai yesterday, Colao said the listing would only be considered after 2011 and after disputes with partner Essar Group and the Indian tax authorities are resolved. It will also depend on local demand for data offerings. “If there’s a good story from a data perspective, and from a regulatory perspective, I’d be likely to look at it,” he said.
