DETROIT: In a two-fingered salute to General Motors' interventionist shareholder Kirk Kerkorian, the automaker's chief executive Rick Wagoner on Wednesday pulled the plug on GM's alliance discussions with Renault and Nissan.

Kerkorian, a Nevada-based octogenarian billionaire and GM's largest single shareholder, had urged the talks on a reportedly reluctant Wagoner - applying further pressure earlier this week by announcing he intended to raise his existing 9.9% stake in the firm.

At a lengthy board meeting on Wednesday, GM directors unanimously decided they could not allow the Renault-Nissan alliance to take a 20% stake in the US giant - thereby becoming its largest stockholder - without digging far deeper into its wallet to reflect its degree of control.

Proclaimed Wagoner: "The value was heavily skewed towards Nissan. We needed to look at good value for GM shareholders. Renault-Nissan made it clear they would not pay any market premium, nor compensate GM to balance the disproportionate impact of expected synergies".

It is not thought, however that Renault-Nissan ceo Carlos Ghosn is overly distraught at GM's decision, which now leaves him free to explore a similar alliance with Ford Motor Company which reportedly, like Charles Dickens' Barkis, "is willing".

Kerkorian's investment company Tracinda said a deal would have given the automaker "substantial synergies and cost savings", adding "we regret that the board did not obtain its own independent evaluation of the alliance."
