A link to the main release on the Central Bank of Ireland's website is below. http://www.centralbank.ie/press-area/press-releases/Pages/2011EU-WideBankStressTestResultsforIrishBanksPublished.aspx
The results published by the Central Bank contain an individual PDF report for AIB detailing the various Eurozone and other Sovereign exposures, including Ireland, as of 31 December 2010. The Sovereign debt exposures are shown starting on page 7 of the PDF report.

I am informed by the bank that an up-to-date disclosure of its Irish Government bond holdings is not currently available on the grounds of commercial sensitivity and would only ordinarily be updated at accounting period ends or as part of other market announcements
