New HP chairman Ray Lane has accused former CEO Mark Hurd of lying to the company board during an investigation, which led to his resignation.
In a letter to the New York Times, Lane, said, "Mr Hurd violated the trust of the board by repeatedly lying to them in the course of an investigation into his conduct."
Hurd was forced to resign in August after the board accused him of making false expense claims and hiding a relationship with HP event contractor Jodie Fisher. Apotheker has replaced him.
Oracle's Larry Ellison was critical of HP for forcing Hurd out, and less than a month later appointed him as co-president at Oracle to replace Charles Phillips, a move that angered HP.
According to the Financial Times, the clash of personalities overlays strategic shifts, pitting HP against Oracle.
To add to the intrigue, Lane is a former president of Oracle, who left the company 10 years ago after falling out with Ellison.
