LONDON (Reuters) - Telecom operator SWISSCOM (SCMN.CH)is reviewing the sale of its Italian broadband firm Fastweb, which is worth up to 5 billion euros ($6.28 billion), sources familiar with the situation said.
The Swiss majority state-owned firm, which has already rebuffed several takeover approaches from VODAFONE (VOD.LO)for Fastweb, is now working with UBS, Vodafone's long-term adviser, to facilitate a deal, said the sources who could not be named because the matter is private.
Swisscom, Fastweb, Vodafone declined to comment; UBS was not immediately available for comment.
