What’s next for Malcolm Turnbull?

PRIME Minister Malcolm Turnbull says he won't stand for the Liberal leadership again if an expected party room meeting on Friday agrees to spill the leadership.

Here's what's going to happen next:

A party room meeting will be called for Friday at noon if the prime minister receives a letter with 43 Liberal MP signatures asking him to do so.

Prior to the proposed meeting time Mr Turnbull expects to receive legal advice over leadership rival Peter Dutton's eligibility to sit in parliament.

If the advice does not clear Mr Dutton over a possible breach of section 44 of the constitution, the meeting will not go ahead and it is likely he would be referred to the High Court by the parliament when it next sits.

In that case, Turnbull would remain leader and prime minister.

If Dutton is not found to potentially be in breach of the constitution, it would clear the way for the Liberal party room meeting to be held.

Treasurer Scott Morrison is reportedly preparing to run against Peter Dutton.

The winner of the Liberal party room ballot will become parliamentary party leader.

Malcolm Turnbull would then tender his resignation to the governor-general and resign from parliament.

The new Liberal leader would be recommended to the governor-general to become Australia's 30th prime minister.

In parliament, which does not sit again until September 10, Labor could move a "no confidence" motion to test the government's majority. The Liberal-National coalition has a one-seat majority. But some Nationals MPs have pledged to sit on crossbench if the prime minister changes.

The government already has budget "supply" until July 2019. * The governor-general would issue the instrument of appointment and oath of office to the new prime minister, and most likely swear in a handful of key cabinet ministers including the treasurer.

If Turnbull resigns immediately a by-election will be needed in the NSW seat of Wentworth.

A half-Senate and full lower house election is due by May 18, 2019.
