Twiggy Forrest attacks election spending

Mining magnate Andrew "Twiggy" Forrest has attacked the election promises of the major parties, saying leaders who can't lead spend instead.

The Fortescue Metals chair was responding to a question about the corporate tax rate, which the federal coalition plans to cut if it wins the July election and spending commitment of both party leaders made so far.

"They would not get a job at the Fortescue Group ... Stop thinking that money is the solution," he told Sky News on Wednesday, adding that if leaders "can't lead, instead they spend".
