MILAN (Reuters) - Italy's Monte dei Paschi di Siena (>> Banca Monte dei Paschi di Siena SpA) said on Thursday it had received two letters from former Italian industry minister Corrado Passera and Swiss bank UBS (>> UBS Group AG), amid reports that the two parties had prepared a proposal to turn around the bank.

The bank's board has started in-depth analysis of the letters and requested data and information to evaluate the terms and conditions, it said in a statement, adding it would give more information when possible.

Three sources said earlier in the day that Passera would submit a rescue plan to Monte dei Paschi's board on Friday, adding UBS had a role in the proposal.
