Federal Treasurer Wayne Swan says former Labor MP Maxine McKew approached him about her political book - but only after she'd finished writing it.
'I was somewhat bemused by that,' Wayne Swan told reporters in Brisbane on Saturday.
'She sent me some questions and I responded. After the book was finished.'
In Tales from the Political Trenches, Ms McKew describes Prime Minister Julia Gillard as being 'disloyal' to Mr Rudd when he was in the top job.
She writes that internal party polling that was critical of the then-prime minister was shopped around to caucus members before the June 2010 coup, when Ms Gillard replaced Mr Rudd.
Ms Gillard has previously asserted that she only made up her mind to challenge on the day she walked into Mr Rudd's office.
On Friday she refused to revisit the matter.
Mr Swan said he hasn't read the book, but after reading media reports he doesn't believe it is balanced.
He brushed aside the suggestion he was disloyal to Mr Rudd, or the question of whether Ms McKew, a former ABC journalist, had ever sat in on cabinet meetings.
'I've already said I don't believe it's a balanced account. That's the end of it as far as I'm concerned,' he said.
The book will be published next week.
