Nine's Political Editor Laurie Oakes has shot down a senior federal government minister’s accusation that Bill Shorten could be responsible for leaking Malcolm Turnbull's Donald Trump roast.

This morning Finance Minister Mathias Cormann suggested Labor leader Bill Shorten was behind the leak from the off the record event, which was published by Oakes yesterday afternoon.

"Bill Shorten will have to clarify today whether it's true that his office was behind leaking those secret recordings and, if so why they thought that was a good idea to do so," he told Sky News this morning.

Oakes was quick to hit back at the suggestion Mr Shorten played any role in the leak.

“Cormann allegation that Mid-Winter Ball material came from Shorten to damage Turnbull is rubbish,” he tweeted.

Oakes also dismissed claims the leak came from the prime minister himself, to combat against criticism he was too fawning towards Trump during their May meeting in New York.

In the video from parliament’s annual Mid-Winter Ball, the prime minister is seen mimicking US President Donald Trump with a cheeky speech, impersonating him and joking about the Russia investigation and “fake polls”.

Journalists attend the annual charity dinner with the understanding that what takes place is off the record, but Oakes, who was not in attendance, received the leaked audio and decided to publish it.

“The idea of the Press Gallery Committee, which hosts this event, declaring it off the record is just ludicrous,” he told Nine presenter Ben Fordham on the TODAY Show this morning.

“Journalists spend their time reporting on confidential or private events.

“We go for leaks … it’s our job.”

Oakes says the fact that this event is singled out and given special treatment is “just so hypocritical”.

“It makes me sick quite frankly,” he said.

Oakes said Mr Turnbull’s speech “was very funny” and a “brilliant performance by Malcolm Turnbull” but questioned whether it was “well judged”.

The political editor pointed out Mr Turnbull’s jokes contrasted with his behaviour when he met with the US president in New York last month.

“He was all over him like a rash, obviously determined to repair relations and come away with Trump as his mate,” he said.

“Now that’s all in danger again.”

Oakes said he thinks Mr Turnbull “would be regretting” the speech this morning.

He said Mr Trump would likely be particularly unhappy with Mr Turnbull’s reference to “this Russian guy”, a joke which took aim at the US investigation into Russian interference in the 2016 US election.

“We know how Donald Trump feels about the claim of links between his campaign and the Russians,” Oakes said.

“He sacked the FBI director over it for God’s sake.

“I don’t think he’s going to be laughing too much.”

Speaking on The Morning Show today Mr Turnbull laughed off the leak, saying the annual event is just about having a laugh.

“We send each other up, we send ourselves up, my speech was in that tradition,” he said with a smile.

“Very Australian.”

The prime minister joked with the hosts about possibly having a future working in stand-up television once he retires from politics.

“Mind you, I think just one audition, I don’t think it demonstrates that I’m up for Saturday Night Live yet.

“I’ve had mixed reviews.”

The relationship between the US president and Mr Turnbull got off to a famously rocky start in January with their first phone call.
