Yesterday Tom Watson, the Labour MP who helped lead the fight to expose the phone-hacking practices of News of the World journalists, queried the company's decision.
"It is remarkably curious that such an generous package is given to Ms Brooks when others have been cut loose," he said. "It is almost as if she hasn't really left the company. I am sure Mr Murdoch will want to explain the decision to his shareholders."
James Murdoch will make his second appearance before the Commons committee after discrepancies arose between his previous testimony and that of his key lieutenants.
During the session he is also likely to be questioned about previous claims that illegal practices did not take place at the Sun newspaper, where Brooks was editor between 2003 and 2009 before being elevated to the role of chief executive of News International.
The investigation into police corruption and newspapers' illegal payments to officers was extended to the Sun last week.
Jamie Pyatt, 49, the first journalist from the title to be arrested under Scotland Yard's Operation Elveden investigation into payments to police officers, has been at the Sun since 1987 and worked under Brooks when she was editor.
Dave Wilson, the chairman of Bell Pottinger, the public relations group hired by Brooks to deal with the fallout from her resignation, declined to comment on the "confidential" details of her severance package. News International also declined to comment.
