Rupert and Wendi Murdoch

Updated with official News Corp response below.

We don’t know what quite to make of this but CtW Investment Group,  a union-affiliated shareholder lobbyist, is raising a stink about News Corp’s new independent director appointment, Accel Partners’ Jim Breyer.

CtW, which claims its affiliations represent pension funds of some 5.5 million Americans or some $200 billion in assets, says Breyer, a venture capitalist best known as an early investor in Facebook, isn’t as independent as the board claims.

In a 1,400-word letter addressed to Viet Dinh, chair of News Corp’s nominating & corporate governance committee,  CtW lists a range of claims about Breyer’s relationships with News Corp, the Murdochs and his record as a director with major names like Wal-Mart and Dell.

A few highlights include:

- News Corp’s “close business relationships” with Accel Management Inc, of which Breyer is a partner

- An Accel investment in a MySpace subsidiary that employed Wendi Murdoch, wife of CEO Rupert Murdoch
