Barclays has announced the appointment of Diony Lebot to the board of Barclays PLC and of Mary Mack to the boards of both Barclays PLC and Barclays Bank PLC.

Diony Lebot joins the Barclays PLC board as an independent non-executive director with effect from 17 March 2025. On her appointment, she will also join the Barclays PLC board sustainability committee.

Lebot brings about 40 years’ experience in banking, financial services and European regulatory matters. She spent her executive career with French bank Société Générale, where she held a number of senior management positions across the bank’s corporate and investment banking activities. Her most recent role was deputy chief executive officer and, prior to this, she was group chief risk officer.

Lebot currently serves as a non-executive director on the boards of Alpha Bank and EQT AB. Until very recently, she also served as a non-executive director of Ayvens (formerly known as ALD SA), a car leasing subsidiary of Société Générale.

Mary Mack will join the boards of Barclays PLC and Barclays Bank PLC as an independent non-executive director with effect from 1 June 2025. Mack also brings expertise in financial services, in particular in the area of consumer banking, having recently retired from an executive career spanning some 40 years with Wells Fargo and several of its predecessor institutions. Her most recent role there was as chief executive officer of consumer and small business banking, prior to which she led Wells Fargo’s community banking and consumer lending business.

Mack currently serves as a non-executive director on the board of Martin Marietta Materials, Inc.

Barclays also announced the retirement from board of Tim Breedon, with effect from 30 April 2025. It thanked him for his contribution through a number of non-executive roles across the Barclays Group, most notably as chair of the Barclays PLC board risk committee.
