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.
They need at least 43 signatures to bring on the meeting after Mr Turnbull defeated Mr Dutton by 48 votes to 35 in a ballot on Tuesday.
Mr Dutton earlier on Wednesday confirmed he was still pursuing a challenge against Mr Turnbull, who chose not to accept the resignations of several ministers who voted against him.
Social Services Minister Dan Tehan denied reports he had shifted support from Mr Turnbull.
“I’ve not resigned and I will not vote against a sitting prime minister,” he said.
Of course, Twitter is taking us through the most important news updates from tonight:
Get ready. Party room meeting tonight. Goodbye Malcolm who doesn’t have the numbers. #auspol
