Tory leadership hopeful Kemi Badenoch claims she didn't agree with her party's decision to extend the Energy Profits Levy.
The former business secretary also accused Labour of "doubling down" on the Conservatives' "mistake" as she visited the North-east on her "listening tour".
She said Labour's planned increase and extension to the windfall tax on oil and gas profits will be "catastrophic".
She said: “I think Labour is doubling down on one of the mistakes we made.Where we got things right, Labour is not doing those things. Where we got things wrong, Labour is doubling down.”
She added: “I think Labour is operating on a mindset from the 1970s and 1980s, that if you just tax things, the money will come in freely. They don’t understand that sometimes businesses will go elsewhere.”
The former business secretary is an early frontrunner in the race to replace Rishi Sunak as Conservative Party leader.
Also in the running are James Cleverly, Robert Jenrick, Priti Patel, Mel Stride and Tom Tugendhat.
