NEW YORK Nov 26 (Reuters) - One of News Corp (NWSA.O) Chief Executive Rupert Murdoch's sons sold about $27.6 million of his shares the media company this week as his investment company purchased a large stake in an Australian radio broadcaster.

The deal was worth about $110 million, according to media reports.

Lachlan Murdoch, who resigned from his executive position at News Corp in 2005 but is still on its board, sold about 2.3 million shares, or just over half of his News Corp common shares, for prices that ranged from $12 to $12.03 per share, according to a filing on Wednesday with the U.S. Securities and Exchange Commission.
