Federal Opposition Leader Tony Abbott has admitted he's not only a reader of "mummy porn", the steamy sub-genre of literature featuring descriptions of sex scenes, he has a preferred author.

Mr Abbott told the Sydney Triple M breakfast show The Grill Team, that he had read both The Bride Stripped Bare by Australian author Nikki Gemmell and Fifty Shades of Grey by British writer E. L. James and that he prefers the homegrown variety.

When asked if he had read the best selling book, Mr Abbott admitted he had. "I've read Fifty Shades of Grey," he said. "I think it's a bit of an eye opener.

"It was interesting, but, I must say ... Nikki Gemmell has a book, The Bride Stripped Bare, which I think is a much better book."
