General Motors is in discussion with billionaire investor Kirk Kerkorian about giving his company representation on GM's board of directors.

Neither GM nor Kerkorian's private equity company Tracinda added any further comment.

In October Kerkorian increased his stake in GM to nearly 10% by acquiring 2.1m shares of GM common stock on the open market. The average purchase price for the shares was US$26.98 per share, for a total purchase price of approximately US$56m.
