FOR IMMEDIATE RELEASE

THOMSON SHAREHOLDERS APPROVE ACQUISITION OF REUTERS

Reuters Shareholders Also Approve Acquisition;

Transaction Expected to Close on April 17, 2008

STAMFORD, Conn., March 26, 2008 — The Thomson Corporation (NYSE: TOC; TSX: TOC), a leading provider of information solutions to business and professional customers worldwide, today announced that its shareholders overwhelmingly approved the proposed acquisition of Reuters Group PLC at a special meeting held today in Toronto.

In separate meetings held today in London, Reuters shareholders also overwhelmingly approved the transaction.  Thomson and Reuters will each now seek court approvals in Canada and the United Kingdom, respectively. The acquisition is expected to close on April 17, 2008.

The Thomson Corporation

The Thomson Corporation (www.thomson.com) is a global leader in providing essential electronic workflow solutions to business and professional customers.  With operational headquarters in Stamford, Conn., Thomson provides value-added information, software tools and applications to professionals in the fields of law, tax, accounting, financial services, scientific research and healthcare.  The Corporation’s common shares are listed on the New York and Toronto stock exchanges (NYSE: TOC; TSX: TOC).

The directors of Thomson accept responsibility for the information contained in this announcement. To the best of the knowledge and belief of the directors of Thomson (who have taken all reasonable care to ensure such is the case), the information contained herein for which they accept responsibility is in accordance with the facts and does not omit anything likely to affect the import of such information.

DEALING DISCLOSURE REQUIREMENTS

Under the provisions of Rule 8.3 of the Takeover Code (the ‘Code’), if any person is, or becomes, ‘interested’ (directly or indirectly) in 1% or more of any class of ‘relevant securities’ of Thomson or of Reuters, all ‘dealings’ in any ‘relevant securities’ of that company (including by means of an option in respect of, or a derivative referenced to, any such ‘relevant securities’) must be publicly disclosed by no later than 3.30 pm (London time) on the London business day following the date of the relevant

1

transaction. This requirement will continue until the date on which the acquisition of Reuters becomes, or is declared, unconditional, lapses or is otherwise withdrawn or on which the ‘offer period’ otherwise ends. If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire an ‘interest’ in ‘relevant securities’ of Thomson or Reuters, they will be deemed to be a single person for the purpose of Rule 8.3.

Under the provisions of Rule 8.1 of the Code, all ‘dealings’ in ‘relevant securities’ of Thomson or Reuters by Thomson or Reuters, or by any of their respective ‘associates’, must be disclosed by no later than 12.00 noon (London time) on the London business day following the date of the relevant transaction.

A disclosure table, giving details of the companies in whose ‘relevant securities’ ‘dealings’ should be disclosed, and the number of such securities in issue, can be found on the Takeover Panel’s website at www.thetakeoverpanel.org.uk.

‘Interests in securities’ arise, in summary, when a person has long economic exposure, whether conditional or absolute, to changes in the price of securities. In particular, a person will be treated as having an ‘interest’ by virtue of the ownership or control of securities, or by virtue of any option in respect of, or derivative referenced to, securities.

Terms in quotation marks are defined in the Code, which can also be found on the Panel’s website. If you are in any doubt as to whether or not you are required to disclose a ‘dealing’ under Rule 8, you should consult the Panel.
