GDANSK, April 30 (Reuters) - The Polish unit of Spanish lender Santander SAN.MC posted a 10.8% jump in first-quarter net profit on Wednesday, driven by higher net interest income and lower costs related to Swiss franc loans.
Santander Bank Polska SPL1.WA, the country's second-biggest lender by market capitalisation, said quarterly net profit amounted to 1.73 billion zlotys ($461.12 million), above the 1.62 billion zlotys expected by analysts in a Reuters poll.
