Prime Minister Malcolm Turnbull arrived back in Canberra on Wednesday morning, just in time for the last two parliamentary sitting days of 2015 – but they’ll be anything but simple.

Mr Turnbull touched down at around 6am after a world trip that took in the Commonwealth Heads of Government meeting in Malta and the climate change conference in Paris.

But the PM will return to question time on Wednesday, where he will face significant Labor probing over his Special Minister of State, Mal Brough, and the ongoing police investigation into his part in the unauthorised disclosure of diaries of former speaker, Peter Slipper.

Labor, in search of its first ministerial scalp, says Mr Turnbull has no choice but to stand Mr Brough aside.

On Tuesday evening, the 60 Minutes program released the full transcript of its interview with Mr Brough, which quashed claims from the under-fire minister that important details were left on the cutting room floor.

Opposition frontbencher Anthony Albanese, accused Mr Brough of misleading the public and the parliament over the affair, while speaking on Sky News.

Meanwhile, the fallout from September’s Liberal leadership spill continues to plague Mr Turnbull and his party’s deputy leader, Julie Bishop.

Ms Bishop is under fire from dumped Prime Minister Tony Abbott, who claims she did not tell him of a February phone call between Mr Turnbull and Scott Morrison, where the former offered the latter the Treasurer role.

Ms Bishop is understood to have listened in on the call and she said she told Mr Abbott that it occurred.

However, Mr Abbott denied he was notified.

“The claim that Julie Bishop made on Channel Nine that she told me about the conversation between Malcolm Turnbull and Scott Morrison that she witnessed is false,” Mr Abbott told Fairfax Media. 

When questioned by The Project on Tuesday evening about the saga, Ms Bishop refused to comment any further, saying herself and Mr Abbott had “different recollections”.

“Well there are obviously different recollections across a whole range of issues,” Ms Bishop said.

“People bring their different perspectives and different recollections to it and I have nothing further to add,” she said.
