Former Liberal staffer Peta Credlin has turned on her old party over Scott Morrison's net zero emissions pledge.
The Prime Minister on Tuesday announced Australia would adopt a net zero by 2050 target to help the world combat global warming, just days before key climate talks in the UK.
The move brought the Government's climate policy into line with Labor's and angered Credlin who has relentlessly spoken out against the target, fearing it will make the country poorer.
Credlin believes nuclear power should be used to generate electricity in Australia to drive emissions down but Mr Morrison has ruled it out because the Labor Party won't support it.
'They are so similar. Other than Tony Abbott stopping the boats back in 2013, what is the difference between these two parties,' she said in a savage put-down on Sky News Australia this week.
Credlin accused Mr Morrison - who in 2019 campaigned against Labor's 'reckless' climate policies - of caving in to 'woke businesses and left-wing Liberals in wealthy inner city seats'.
'When people go to the ballot box they thought they were voting for a conservative party last time round they will look very, very carefully this time round,' she said.
'I think we're going to see a lot of movement of that underlying conservative Liberal vote and conservative National Party vote into minor parties on the right.
'I think that's diabolical for a prime minister that's already starting from behind,' she said in reference to the latest Newspoll survey which shows Labor leading the Coalition by 54 to 46 per cent in the two party preferred vote.

Credlin, who was former Prime Minister Tony Abbott's Chief Of Staff when he won a landslide election after vowing to repeal Labor's so-called 'carbon tax', said she was 'at war' with her old party.
'I think this is a death knell on the Government… on this issue alone I have a war with my former party on this,' she said.
Opponents of the net-zero target believe it will cost jobs in traditional high-polluting industries such as coal mining and fear it will see electricity prices rise.
A chorus of international and domestic critics including David Attenborough blasted the plan for lacking detail and failing to increase 2030 emissions reduction targets.
However, Mr Morrison rejected the barrage of disapproval, saying it came from people who wanted to tax, regulate and shut industries down.
Mr Morrison says his plan to achieve it using technologies such as solar power and clear hydrogen will create jobs, keep energy prices low and leave Aussies $2,000 better off compared with taking no climate action.

Credlin also savaged the Morrison Government in an opinion piece in The Australian newspaper where she criticised his deal to acquire nuclear powered submarines from the US and the UK even though the boats may not be ready until 2040.
'Having policies for 2050 and 2040, but not for next year, is hardly a good position to be in eight months out from an election, with a wafer-thin majority, an unfavourable redistribution, behind in the polls, and seeking a fourth term,' she wrote.
In the article titled 'How did Morrison let his government flounder like this?' Credlin slammed the Prime Minister for failing to pass laws to cement religious freedom and set up a promised federal anti-corruption body.
She also blasted what she called his 'refusal to call out the repeated failure of premiers to adhere to national cabinet decisions' on managing coronavirus.

When he announced his net zero plan this week, Mr Morrison said Australia can reach net zero emissions by relying on technology such as solar power and green hydrogen and without introducing any taxes - but he did not announce any new initiatives or funding.
By 2050, Australia's electricity generation will cause up to 97 per cent fewer emissions than in 2005, using renewables but with a small amount of gas-fired power remaining.
Nuclear power is off the table but Mr Morrison did not rule out building more coal-fired power stations in a move that will disappoint allies such as the UK who want to phase out coal around
