FOR IMMEDIATE DELIVERY                                    29 JULY 2005

                           Allied Irish Banks, p.l.c.

                           New Bankcentre Development

Allied Irish Banks, p.l.c. ("AIB") (NYSE: AIB) today announces that it has
completed certain transactions in relation to part of its Bankcentre site (the
site) at Ballsbridge, Dublin 4.

The site has been sold to the Serpentine Consortium, a syndicate of private
individuals and companies assembled by AIB Private Banking and Goodbody
Stockbrokers. The Serpentine Consortium was selected following an open market
competitive bidding process.

Separately the Serpentine Consortium has engaged Blogram Limited, a subsidiary
of AIB, to develop the site.

The total sum to be paid by the Serpentine Consortium for the purchase and
subsequent development of the site is EUR367.75 million in cash. The book value
of the site is EUR1.2 million.

The development will extend to a total area of 324,766 square feet. Upon
completion, it is intended that the development will be let to a company in the
AIB Group for a period of up to 31 years under a lease with a break clause,
exercisable by the tenant after 23 years. The initial annual rent payable by the
tenant will be EUR16.117 million per annum and will be subject to adjustment in
subsequent five year rent reviews. It is anticipated that this cost will be more
than offset by savings on rent and other costs elsewhere.

The capital benefit (i.e. the profit after taxation) to AIB generated from the
transactions is in the region of EUR160 million. This benefit will be derived 
over 3 years, beginning in 2005. AIB will reinvest the proceeds of the 
transactions in its core banking business.
