Ladies and Gentlemen:
We have acted as U.S. counsel to RELX Capital Inc., a Delaware corporation (the “Issuer”) and RELX PLC, a public limited company incorporated in England and Wales (the “Guarantor”),
in connection with the preparation and filing by the Issuer and the Guarantor with the Securities and Exchange Commission (the “Commission”) of a registration statement on Form F-3 (the “Registration Statement”),
under the Securities Act of 1933, as amended (the “Securities Act”), relating to the registration under the Securities Act and the proposed issuance and sale from time to time pursuant to Rule 415 under the Securities Act
of an indeterminate principal amount of debt securities of the Issuer in one or more series (the “Debt Securities”) and guarantees of the Debt Securities by the Guarantor (the “Guarantees”). The Debt Securities
will be issued under an indenture, dated as of May 9, 1995, as amended and supplemented (the “Indenture”), among the Issuer, the Guarantor and The Bank of New York Mellon, as trustee (the “Trustee”), principal
paying agent and securities registrar.
In that connection, we have examined originals, or copies certified or otherwise identified to our satisfaction, of such documents, corporate records and other instruments as we have
deemed necessary or appropriate for the purposes of this opinion, including: (a) the Amended and Restated Certificate of Incorporation of the Issuer, as filed with the Secretary of State of the State of Delaware on April 14,
2015; (b) the Amended and Restated Bylaws of the Issuer, as adopted on April 21, 2015; (c) resolutions adopted by the Board of Directors of the Issuer on April 11, 2025; (d) the Registration Statement; (e) the Indenture; and (f)
the form of note (global registered form) and the form of note (definitive form) relating to the Debt Securities included in the Registration Statement as Exhibits 4.10 and 4.11, respectively.
In expressing the opinions set forth herein, we have assumed, with your consent and without independent investigation or verification, the genuineness of all signatures, the legal capacity
and competency of all natural persons, the authenticity of all documents submitted to us as originals and the conformity to authentic original documents of all documents submitted to us as duplicates or copies. We have also
assumed that the Indenture has been duly authorized, executed and delivered by the Trustee thereunder.
