LONDON, Sept 10 Spain's Santander (SAN.MC) is set to win the auction to buy Allied Irish Banks' (ALBK.I) controlling stake in Poland's Bank Zachodni WBK BZWB.WA, the Financial Times said on Friday.
The newspaper said on its website, citing people close to the situation, that Santander has won the bidding for the 70 percent stake.
Final bids have been submitted from Santander, Poland's largest lender PKO Bank Polski PKOB.WA and French bank BNP Paribas (BNPP.PA).
AIB has said it wants to have a deal for Zachodni agreed by the end of September. Ireland's second-largest bank is selling its stake in Zachodni as part of a plan to raise 7.4 billion euros in capital requested by the Irish regulator.
AIB, Santander and Zachodni all declined to comment. (Reporting by Steve Slater; Editing by Greg Mahlich)
