Filing under Rule 425 under the Securities Act of 1933 and deemed filed under Rule 14d-2 of the Securities Exchange Act of 1934 Filing by: Carnival Corporation Subject Company: P&O Princess Cruises plc. SEC File No. of Princess: 001-15136 [GRAPHIC OMITTED] [LOGO - CARNIVAL CORPORATION] Carnival Corporation Carnival Place 3655 N.W. 87 Avenue Miami, Florida 33178-2428 United States The Board of Directors P&O Princess Cruises plc 11-12 Charles II Street London SW1Y 4QU United Kingdom 26 February 2002 For the attention of Lord Sterling of Plaistow Dear Lord Sterling, I am writing on behalf of the board of Carnival firstly to thank you for the courtesy you showed the Carnival team at your EGM. Your polite and impartial chairing of the meeting was much appreciated, as was your decision to let Howard and me address your shareholders directly. I am aware that since the EGM you have continued to express your concerns about the deliverability of our Increased Offer. As all parties have acknowledged, the regulatory review process will be lengthy and involved. However, as your shareholders have now chosen to allow both proposals to be reviewed by the relevant regulatory authorities before making their decision, we continue to believe their interests will be best served by obtaining regulatory clearance for both proposals. Indeed, as we have said since December, we believe that both proposals are similarly situated for purposes of the regulatory reviews and face the same issues based on the same basic facts. I would like to take this opportunity to confirm that Carnival remains fully committed to working constructively with the regulatory authorities in the US and Europe and to pursuing those regulatory reviews to their ultimate conclusion. In the interests of your shareholders, who have clearly expressed their wish to have the opportunity to consider Carnival's Increased Offer after regulatory clearance has been obtained, I hope that you and your team will now work constructively to secure regulatory clearance for both proposals without prejudice to either. We would like to propose that our advisors consult with your advisors to coordinate our respective responses to the ongoing reviews. As you are aware, our Increased Offer is conditional on P&O Princess terminating the Joint Venture Agreement through the commercial benchmark mechanism. You confirmed in your announcement of 4 February 2002 that your Board has been advised that "it has no express or implied obligation under the Joint Venture Agreement or otherwise to cause the benchmarks to be satisfied." As we have said in our previous letters, we are prepared to discuss with you ways in which we can together develop a DLC structure. Many of your shareholders have indicated to us that they would find this type of structure attractive. Under a DLC structure, we envisage that the economic interest of P&O Princess would reflect the 550p per share valuation of P&O Princess under our Increased Offer. This would be equivalent, based on the current market values of P&O Princess and Royal Caribbean, to P&O Princess shareholders receiving 62 per cent. of the equity in the proposed combination with Royal Caribbean. I hope that we can together ensure that both proposals obtain regulatory clearance and are capable of completion. We believe that this is in the best interests of P&O Princess shareholders who can then make their choice based on valuation and strategic criteria alone.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS Certain statements in this announcement constitute "forward-looking statements" within the meaning of the US Private Securities Litigation Reform Act of 1995. Carnival has tried, wherever possible, to identify such statements by using words such as "anticipate," "assume," "believe," "expect," "intend," "plan" and words and terms of similar substance in connection with any discussion of future operating or financial performance. These forward-looking statements, including those which may impact the forecasting of Carnival's annual cost savings that underlie estimates of synergies and one time costs to implement synergies, net revenue yields, booking levels, price, occupancy or business prospects, involve known and unknown risks, uncertainties and other factors, which may cause Carnival's actual results, performances or achievements to be materially different from any future results, performances or achievements expressed or implied by such forward-looking statements. Such factors include, among others, the following: general economic and business conditions which may impact levels of disposable income of consumers and the net revenue yields for Carnival's cruise products; consumer demand for cruises and other vacation options; other vacation industry competition; effects on consumer demand of armed conflicts, political instability, terrorism, the availability of air service and adverse media publicity; increases in cruise industry and vacation industry capacity; continued availability of attractive port destinations; changes in tax laws and regulations; Carnival's ability to implement its brand strategy, Carnival's ability to implement its shipbuilding program and to continue to expand its business outside the North American market; Carnival's ability to attract and retain shipboard crew; changes in foreign currency rates, security expenses, food, fuel, insurance and commodity prices and interest rates; delivery of new ships on schedule and at the contracted prices; weather patterns; unscheduled ship repairs and dry-docking; incidents involving cruise ships; impact of pending or threatened litigation; and changes in laws and regulations applicable to Carnival. Carnival cautions the reader that these risks may not be exhaustive. Carnival operates in a continually changing business environment, and new risks emerge from time to time. Carnival cannot predict such risks nor can it assess the impact, if any, of such risks on its business or the extent to which any risk, or combination of risks may cause actual results to differ from those projected in any forward-looking statements. Accordingly, forward-looking statements should not be relied upon as a prediction of actual results. Carnival undertakes no obligation to update publicly or revise any forward-looking statements, whether as a result of new information, future events or otherwise.
