FOR IMMEDIATE RELEASE                                              11 JUNE 2003

                           Allied Irish Banks, p.l.c.

                                 Trading Update

Allied Irish Banks, p.l.c. ("AIB") (NYSE:AIB) is issuing the following update on
trading before its half-year close period.

Growth in our Irish and British retail and commercial banking businesses
continues to be excellent. In both islands we are growing faster than our
competitors and we continue to target underlying double digit operating
performance growth in these businesses. In Ireland we are winning a greater
share of customers' business and in Britain we are gaining more customers within
our chosen niches. The Capital Markets Division continues to display resilience
in difficult market conditions. Performance in Poland is weaker, primarily due
to the impact of sharp interest rate cuts on our deposit base. Throughout our
business, we relentlessly focus on productivity and expect to maintain a
positive underlying gap between income and cost growth for the year 2003.

The weakening of the US dollar, sterling and Polish zloty against the euro will
give rise to an estimated negative currency impact of 4% on the translation of
earnings from our non euro denominated businesses, despite an active hedging
policy. Accordingly, we are now targeting low single digit growth in underlying
adjusted Group earnings per share for 2003.

At the interim stage, we expect an out-turn of marginal underlying adjusted
earnings per share growth because of:

  - Particularly strong interest rate management performance in the first half
    of 2002.

  - Lower Allfirst performance in the first quarter compared with 2002,
    notably a reduced yield from the restructured investment securities
    portfolio.

  - Significant, non recurring income generated by Ark Life in the early
    months of 2002 during the closing stage of the Government sponsored savings
    campaign (SSIAs).

At our annual results presentation in February our guidance for 2003 excluded
certain significant / one off items. We indicated then that we would seek to
clarify their effect in this trading update, including the impact of the merger
of Allfirst with M&T which was completed on April 1st 2003. We have appended an
analysis of our 2002 results to facilitate year on year comparisons, and the
following table and comment is intended to provide further clarification.


2002 Adjusted Earnings per Share                           123.0c
Significant / one off items:
 1. FRS 17                                   c. (5.9c)
Reduction in other finance income
Government levy                              c. (3.5c)

Total significant / one off items            c. (9.4c)


        A post tax gain of approximately EUR450m will be recognised on the
        merger of Allfirst with M&T. Good progress is already evident in the
        integration of Allfirst into M&T, and the 2003 results will include
        AIB's 22.5% share of a one time M&T restructuring charge.

Republic of Ireland Division

Good economic management is essential to ensure Ireland remains well positioned
to benefit from a potential upswing in the global economy, which we expect to
gather momentum over the coming months. This year we anticipate GDP growth of
around 2% in Ireland.

Customer demand for our retail and commercial banking products and services is
very strong. Our primary focus on doing more business with our existing
customers is being tangibly reflected in increasing revenues and market shares.
This is particularly evident in our loan book which is on target to grow by
around 15% this year. Home mortgages continue to be the fastest growing product
category and we are extending our rate of growth relative to the market without
dilution of our credit criteria. Similarly, in our other loan portfolios,
volumes are ahead of expectations and there is a good pipeline of new business.
Deposits are increasing in line with expectations.

The repositioning of Ark Life in the bancassurance market, referred to at our
2002 results presentation, is progressing well. Performance in the first half
will be lower due to the closing of the SSIAs in 2002, however we expect the
second half will be better, reflecting the repositioning of the business.

Great Britain and Northern Ireland Division

The deepening and extending of this high quality franchise is being reflected in
strong loan and deposit volumes, both of which are recording good double digit
annual increases. Our drive to be recognised as the bank of choice in chosen
market segments in Great Britain is being rewarded by buoyant demand from new
and existing customers. Our differentiated approach to customer relationship
building and our growing presence in mid market sectors is being supported and
underpinned by significant investment in people and new locations. A similar
approach to the Republic of Ireland business model is being implemented in
Northern Ireland where we continue to gain market share in key product
categories.

Capital Markets Division

Operating performance from our corporate banking business continues to be
strong. We are seeing good loan growth in our international businesses, notably
in Great Britain and New York. Conversely, loan demand from our domestic
corporate banking customers remains subdued. Good fee income is being generated,
notably from our highly successful CDOs.

Our treasury performance is in line with expectations. The significant benefit
of being positioned for falling interest rates in 2002 will not be repeated as
positions run off. Our current utilisation of market risk limits is low.
Investment banking and asset management revenues are also being affected by the
overall low levels of activity and market conditions generally.

Allied Irish America, now part of Capital Markets division, continues to perform
well.

Poland Division

The building of our Polish franchise is largely complete, enabling us maintain
good cost discipline and positioning us to deliver medium term profit growth.
The current low level of economic activity however is militating against
significant loan growth. We are maintaining our resolve not to compromise asset
quality, which is improving, and accordingly loan volumes this year will
increase by a single digit percentage. The very steep fall in interest rates
from 19% in 2001 to 5.5% recently, which we welcome as a prerequisite for future
growth in the economy, is having a significant adverse effect on interest income
from deposits, in what is still a heavily deposit led bank.

USA

While still at an early stage following the merger, our interaction with our
colleagues in M&T is very positive and we are confident as to the growth and
synergies this partnership will deliver. We continue to expect that the
combination of earnings generated by Allfirst in the first quarter of this year,
our 22.5% share of M&T's net income for the subsequent quarters and the impact
of the recently completed buyback of 35.9m shares will give a marginally
accretive overall result in 2003 relative to the contribution of Allfirst to
2002 group earnings.

Costs

We are targeting an underlying reduction in the cost/income ratio this year.
Underlying cost growth for the Group is expected to be around 5%.

Asset Quality

Our retail and commercial loan portfolios are all retaining a high level of
quality and resilience, with no signs of material disimprovement. We remain
prudent and conservative in our monitoring of corporate credit exposures and do
not anticipate loan loss experience that will exceed our expected loan loss
parameters. We continue to expect the overall full year provision charge not to
exceed 40 basis points as a percentage of average loans. We deem provision
coverage, both specific and general, to be good.

Margins

Changing product mix is currently the main factor affecting the net interest
margin and we expect attrition of around 20 basis points for the year. To date
the lower interest rate environment has been managed to minimise the impact on
margins (although, as already noted, the dramatic reduction in Poland has had a
negative effect). Further significant cuts would compress margins on the
liability side of the balance sheet and have a negative endowment effect as we
reinvest maturing investment funds.

Capital Management

In the transition of Allfirst into M&T, the weighted average number of AIB
shares for earnings per share purposes increased by approx. 16m. These shares
were previously held in trust for Allfirst staff compensation plans. The impact
of this increase in our share base will be to dilute 2003 earnings per share by
approx. 2.0c, about 1.5%, and is included in the guidance in this update.

We have recently concluded the share buy back programme undertaken following
completion of the M&T / Allfirst merger. A total of EUR483m was returned to
shareholders through the repurchase of 35.9m shares. The Group's capital ratios
remain very strong and a further rolling share buyback programme is one of the
actions we intend to pursue as part of our ongoing capital management
activities.

Group results for the half-year ended 30th June 2003 will be announced on 29th
July 2003.

The above table shows the profit / (loss) on ordinary activities before taxation
by business segment for the half-year 30 June 2002 and the year 31 December
2002. The business segment profits have been restated to reflect the following:


  - The movement of Allied Irish America from USA Division to Capital Markets
    Division

  - The allocation of pension costs across business segments has been amended.
    The normalised pension contribution rate appropriate to individual pension
    schemes has been charged to each operating division. The residual impact of
    the expected return on pension scheme assets and the interest on pension
    scheme liabilities is recorded in Group.
