       GDANSK, Aug 23 (Reuters) - Poland's biggest bank, PKO BP
        , is expected to report a 13% year-on-year increase in
second-quarter net profit, but a drop of as much as 67%
quarter-on-quarter due to costs related to Swiss franc loans, a
Reuters poll showed on Wednesday.
    State-run PKO BP is expected to report a net profit of 476
million zlotys ($115 million) for the quarter, the survey of
five banks and brokerages showed.
    That would result in a net profit of 898 million zlotys for
the first half of 2023.
