John Banks slams his fist into the palm of his hand. It is all about adding theatrical effect to what he is about to say.
"It's called fight back. It's called fight back," he repeats, before adding another word - "hard".
The Act leader and Epsom MP has said little since police last month found no grounds for prosecution following a complaint about donations to his Auckland mayoral campaign in 2010 and the accuracy of his election return.
He now has plenty to say about the three months he spent in limbo while waiting for the results of the police investigation.
"I found it deeply offensive, much of what was said, written and broadcast during that time because, for all my faults, anyone who knows me would never believe I would go out deliberately and falsify a return," Mr Banks told the Weekend Herald.
