AIB has denied two fresh charges of ripping off its customers.
It is alleged that the country's largest bank failed to adequately warn some elderly customers four years ago of the risk of moving money from cash deposits to investment policies, leading to a loss of money.
The second charge accuses some branches of charging double commission to customers buying dollar drafts using dollars. But the bank last night denied it had acted improperly.
The claims come after AIB's admission last week it had charged an extra 0.5% on foreign exchange transactions over the past eight years, which netted an extra €14m in charges.
