Liberals Try To Force Turnbull Challenge

Liberal MPs are reportedly trying to get Malcolm Turnbull to call a party room meeting to face a leadership challenge from Peter Dutton on Wednesday night.

UPDATE: A second vote in unlikely on Wednesday night.

A group of Liberals are pushing for a second vote on the leadership, reportedly circulating a petition for Malcolm Turnbull to call another party room meeting.

They need at least 43 signatures -- a majority of the party room -- to bring on the meeting and have another leadership vote. It would be the second in the space of two days, after Turnbull defeated Dutton by 48 votes to 35 in a snap ballot on Tuesday.

The sudden push, coming late on Wednesday night, for a second vote is a sign of confidence from Dutton backers that they think the former home affairs minister has the support needed to topple the PM.

It is unclear how many, if any, MPs have backed the push for a meeting. Even if the petition is successful, there is no guarantee when the meeting will be held.

Dutton earlier on Wednesday confirmed he was still pursuing a challenge against Turnbull, admitting he was whipping support for a potential second vote from his colleagues.
