A pro-family political party in Australia has expelled one of its members reportedly over pornography scandals.

Victorian Senator Steve Fielding's Family First party has recalled the endorsement of Andrew Quah, 22, on Saturday.

Quah, who claims he was set up by his political adversaries, has reportedly admitted posing for two revealing images where in one, he was partly undressed, and in the other, he is clutching his private parts.

The photos were circulated via email across the country.

Also, Quah has admitted downloading porn on the web, a fact that rocked the pro-family party whose key concern is a crackdown on internet pornography.
