NATIONAL Irish Bank is to seek 100 voluntary redundancies and close 20 branches.
The bank, which is owned by Denmark’s Danske, previously shut down 25 branches in December 2009.
Nine remaining outlets will no longer provide transaction services and will be converted to personal banking units providing advice.
The bank wants to move away from an "unsustainable and transaction-based banking business model."
Lodgement facilities will be available through An Post while customers will also have access to a phone service.
NIB will also be rebranded Danske Bank while the the day-to-day running of customer accounts will not be affected, according to the bank.
