BREAKING: Peter Dutton To Challenge Malcolm Turnbull Again

After failing to oust PM Malcolm Turnbull only days ago, Peter Dutton has tweeted that he plans to contest the leadership yet again.

A few minutes ago I spoke with Malcolm Turnbull to advise him I believed the majority of the party room no longer supported his leadership. Accordingly, I asked him to convene a party room meeting at which I would challenge for the leadership of the Parliamentary Liberal Party.

A defiant prime minister is holding on to his leadership with support from his two key lieutenants, Treasurer Scott Morrison and Finance Minister Mathias Cormann.

Mr Dutton's supporters circulated a letter on Wednesday night calling for the party room to meet.

"I understand there's a petition. I understand that a couple of hours ago there were nine signatures on it," Liberal MP Jane Prentice told reporters on Wednesday night.

It was unclear how many MPs had actually seen and signed the letter and if any cabinet ministers were willing to shift their support from Mr Turnbull.

Mr Dutton admitted he's calling Liberals to win support for a second challenge after failing 48 votes to 35 in a snap leadership ballot on Tuesday.

The electorate, however, appears to be supporting Mr Turnbull.

A Morgan poll of more than 1200 voters picked Mr Turnbull as the better prime minister over Mr Shorten, 52 per cent to 44.5 per cent.
