SYDNEY (Reuters) - Former Australian Home Affairs Minister Peter Dutton has launched a bid to unseat Prime Minister Malcolm Turnbull, saying a majority of the party no longer has faith in his leadership.

Dutton, who was a Queensland policeman before being elected to parliament, is a polarizing figure best known for enforcing tough immigration policies.

Despite narrowly beating Dutton in a party-room vote earlier in the week, Turnbull said he will hold a second leadership vote on Friday if the majority of Liberal MPs sign a petition supporting the move.

The following are a selection of notable quotes from Dutton in recent years.

“I discriminate not on somebody’s ethnic background, not on their religion, not on their country of origin, but on the fact that they have conducted themselves against the law, outside of the law.”
