Patricia Dunn, the chairman of Hewlett-Packard, on Friday hit back at critics who accused her of mismanaging an investigation into boardroom leaks.
Ms Dunn said Tom Perkins, the venture capitalist who resigned in May in a dispute over investigators’ tactics, had “gone ballistic and accusatory in my direction” because she “refused to go along with his plan to cover up” the leaks.
She said: “I advised the board at every executive session that the leak investigation was ongoing. Tom himself advocated the use of lie detector tests.”
Mr Perkins could not be reached for comment on Friday.
Ms Dunn has faced calls to resign over her handling of the probe. HP revealed this week that private investigators impersonated board members and journalists to gain access to their telephone records – a move that the California attorney general has denounced as illegal.
HP’s board was due to meet on Sunday. Ms Dunn said: “I trust our board totally. If they ask me to step aside, I absolutely will.”
Ms Dunn said she “turned to resources the company uses to handle breaches of confidentiality” to uncover the leaks, which revealed board deliberations over Carly Fiorina, who was ousted as chief executive last year.
She said those sources assured her the investigation was “not only fully legal but fully compliant with HP’s standards.”
However, Ms Dunn said she chose not to ask about the details of the probe because she was a subject of the investigation herself.
