A large Australian super fund has joined other News Corp shareholders in their campaign to remove Rupert Murdoch as chairman ahead of this year's annual general meeting.

A resolution to that effect has already been filed in the US and overnight Hermes, a British fund controlling $39 billion in assets, backed the call to break the Murdoch family's stranglehold on the business.

Now Australia's First Super, which manages around $1.7 billion of member funds, has announced it will also be voting against the re-election of Mr Murdoch and four other directors, including James and Lachlan Murdoch.

First Super says other Australian industry super funds are likely to do the same, following a recommendation by the Australian Council of Superannuation Investors.

The fund's chief executive Graeme Russell says it will also be voting against News Corp's remuneration report, because its executives are paid "outrageous amounts of money."

"The aggregate cash pay of their top six executives was $US65.5m, more than three times the amount received by the top nine executives of BHP Billiton, and they are by no means underpaid," he noted in a statement.

"We don't believe that any senior executive is worth four or five hundred times the wages paid to the employees who do the work, produce the product and generate the revenue and profits."

Annual revolt

This is the second year the Murdochs will face a shareholder revolt at the News Corp AGM to be held on October 16.

Last year it ended with the majority of independent shareholders voting against the re-election of James and Lachlan Murdoch.
