MILAN, Sept 8 (Reuters) - Bidders for Italian stock market Borsa Italiana have valued it at between 3.3 and 3.7 billion euros ($3.89-$4.37 billion), Italian daily MF wrote on Tuesday, citing market sources.
The London Stock Exchange , which bought Borsa Italiana for 1.6 billion euros in 2007, put it on sale to win European Union approval for its $27 billion takeover of data company Refinitiv.
The EU's competition regulator expressed concern in June that a combination of LSE's LSE.L bond-trading platform MTS and Refinitiv, which owns bond platform Tradeweb, would have a large market share in European government bond trading.
A month later, LSE CEO David Schwimmer said the London exchange might sell off MTS or the entire Borsa Italiana group.
The deadline for non-binding bids for all of Borsa Italiana group, which besides the 62.5% of the bond-trading platform MTS also controls the Milan stock exchange and a clearing and settlement system, is Sept. 11, sources said in August. = 0.8472 euros)
