Tony Abbott is not happy as he had just announced that he and his deputy would be the only ones talking to the independents.
Remember Christopher once said that he wanted to be Prime Minister and he didn't care for which party.
The depth of his belief is obvious, he has none, just ambition.
While the minister for ageing, he overheard to say that he didn't like old people but it was a step upward.
He is an extremely ambitious person, he loves power and wants more, he obviously thought he would gain more press for himself with his latest remarks.
They say he said it was a joke, he didn't mean anything by it, he was not trying to preempt Tony.
