(Reuters) - General Motors Co GM.N said on Friday proxy adviser Glass Lewis & Co LLC recommended shareholders to vote for GM's board nominees and against Greenlight Capital's proposal at the company's annual shareholder meeting in June.

Hedge fund manager David Einhorn’s Greenlight has been pressuring GM to split its common stock into two classes to help boost its share price.

Glass Lewis agreed with the automaker that "there are a number of risks and uncertainties associated with Greenlight's plan and that it is speculative in nature," GM said. (bit.ly/2rYpykb)
