DUBLIN (Reuters) - Royal Bank of Scotland's (>> Royal Bank of Scotland Group plc) Irish unit Ulster Bank will shut nearly 10 percent of its branches, becoming the latest lender to scale back in the wake of Ireland's banking crash.

Local banks and foreign lenders servicing the Irish economy have shut branches and shed thousands of jobs since the crisis hit in 2008. Ulster has already made hundreds of redundancies and last year announced a second round of job cuts involving the departure of 950 staff. It had cut 1,000 jobs in 2009.

The latest redundancies were delayed by an IT failure at the bank last June, which cost Ireland's third-largest lender tens of millions of euros in compensation after salaries failed to appear in accounts and customers' household bills went unpaid.

Ulster said on Thursday it was reviewing its 226 branches, which are spilt between the Republic of Ireland and Northern Ireland, and expected to be able to provide customers with further details of the closures in the next few weeks.

It said it would close around 20 branches and sub offices in Ireland this year as a result of the review.

Rival Allied Irish Banks (>> Allied Irish Banks PLC), Ireland's second-largest bank, is closing a number of branches as it trims its workforce by almost 20 percent, while permanent tsb (>> Permanent TSB Group Public Hldg Ltd Co) is shutting 17 percent of its 92 branches.

Denmark's Danske Bank (>> Danske Bank A/S) closed its network of branches last year, although it continues to serve customers through telephone and mobile banking.

Bank of Ireland (>> Bank of Ireland), the only domestic Irish lender to avoid falling under full state control, has not closed any branches since the crisis, despite also cutting its staff numbers substantially.
