Australian Greens Leader Bob Brown says the Gillard-Abbott disagreement over a last week election campaign debate has become a farce.
"There should have been three debates, with three leaders, with the public involved, arbitrated by an Independent Election Debates Commission," Senator Brown said.
"Both major parties are haemorrhaging votes over this.
"People tell me they are fed up.
"If Tony Abbott insists it be tonight and Julia Gillard insists it be tomorrow night I can fill the void and will willingly step into both debates, featuring the economy," Senator Brown said.
