Suella Braverman has told GB News she would be happy if Nigel Farage pursued socialist policies if he were prime minister.
The former home secretary, who is one of the most senior former Conservative defectors to Reform UK, said she supports the state nationalising failing British industries.
Mrs Braverman also revealed she has yet to receive a personal apology from Kemi Badenoch after the Tories wrongly suggested she had mental health issues before defecting to Mr Farage's party.
She spoke to the People's Channel as Mr Farage looks set to announce his shadow cabinet to "get the party into shape" in preparation for a general election.
Reform UK has been criticised by those on the right for backing left-wing policies, such as nationalising parts of the UK steel industry and lifting the two-child benefit cap.
However, Mrs Braverman told GB News' Chopper's Political Podcast she was not troubled by these policies.
Asked if she was "happy" if her party pursued "socialist" policies, Mrs Braverman said: "I am actually.
"So I think there's actually a case for — if we are serious about industrialising our country and a renaissance of our industry — state involvement in our industries.

"Our heavy industries have been abandoned and unable to compete against a more powerful and ascendant East.
"And so I do think there is a very strong case.
"The benefit will be more jobs.
"The benefit will be more growth for our economy.

The Tories came under fire for saying Mrs Braverman had mental health issues when she quit the party a few weeks ago.
The party later withdrew the remark.
However, Mrs Braverman disclosed she had not had a personal apology from Tory leader Ms Badenoch, saying: "They haven't actually apologised to me directly.
"The leader has said she's apologised, but no one has apologised."
"There's been no apology directly to me, despite their saying there's been an apology.
"And that is what the Conservative Party is today."
She added: "It says more about them than it does about me."
Mrs Braverman was dismissive of Mrs Badenoch's commitment to taking the UK out of the European Convention on Human Rights (ECHR) if the Tories win the next election.
She said: "I don't believe they will.
"There's more chance of me joining Zack Polanski's Green Party."
