Anglo Irish Bank's chief executive said an estimate of 25 billion euros ($32 billion) for the final bill for bailing out the nationalized lender was broadly correct, in an interview on Tuesday.

"We think that that is probably about right going back to a 60-65 percent number around haircuts on the remaining NAMA book and given the level of provisioning," Mike Aynsley told Reuters.

Aynsley also said he expected the European Commission to issue its opinion on the future of Anglo Irish in September.

He said his preference was still for the group to be split into a good bank and a bad bank.

Irish officials signaled on Monday a gradual wind-down may be pursued.
