POWER OF ATTORNEY

Reference is hereby made to the proposed registration by Barclays PLC (“Barclays”) under the U.S. Securities Act of 1933, as amended (the “Securities Act”) of (i) debt securities, (ii) contingent convertible securities and (iii) ordinary shares, in each case which may be offered and sold by Barclays (collectively, “Securities”). Such Securities will be registered on one or more registration statements on Form F-3 (including amendments thereto), or on such other form or forms promulgated by the U.S. Securities and Exchange Commission (the “SEC”) as may be necessary or advisable to effect such registration (each such registration statement, a “Registration Statement”). In connection with such Registration Statement, Barclays will file a Form F-N to appoint an agent for service of process in the United States (the “Form F-N”).
