Ulster Bank aiming for 'normal service' by 16th
The Ulster Bank is to open 10 branches on 12 July, a traditional bank holiday in Northern Ireland.
Thousands of customers across the island of Ireland have been affected by a computer failure at the bank's parent company RBS on 19 June.
It is the first time ever that Northern Ireland branches will remain open during the holiday, which marks the 1690 Battle of the Boyne.
The bank said most problems would be resolved by its 16 July deadline.
The BBC's Ireland Correspondent Mark Simpson spoke to the bank's head of retail in Northern Ireland, Stephen Cruise.
