AIB's executive chairman has told staff there will be job losses as a result of a restructuring plan which will make the bank smaller.
In an e-mail to staff, David Hodgkinson said the bank would prefer that most redundancies would be voluntary, and said job losses would be phased throughout the bank.
He said the findings of a review of AIB's future had been submitted to the board, and would now be discussed with the regulator and the Government.
Mr Hodgkinson said the review covered the bank's future size, its management structure and staff numbers.
The e-mail also said that the bank was now selecting people for its top management positions, and would announce appointments 'as soon as possible'.
