One of the sources said Deutsche Boerse and Swiss stock exchange Six had also presented bids for the MTS platform used for trading Italy’s huge sovereign debt.

The non-binding bids for a stake of more than 60 percent in MTS are believed to be in the range of €300-€350 million ($355-$410 million), sources said.

Italian daily la Repubblica reported on Saturday that the US stock exchange Nasdaq had also presented a non-binding offer, as well as the bidders cited to Reuters.
