The deputy leader of the Labour party Harriet Harman has said she will call a vote in the House of Commons on whether Jeremy Hunt's actions should be referred to the independent investigator on the ministerial code.
She told BBC Breakfast that Mr Hunt "broke the ministerial code" and "as far as David Cameron is concerned [that] is perfectly acceptable".
"It is not acceptable to us that these rules should have been broken and we are going to call a vote on it in the House of Commons."
Labour's deputy leader Harriet Harman has accused the Culture Secretary Jeremy Hunt of making "a political decision" about the BSkyB bid when he was supposed to be acting impartially.
In an interview in ITV Daybreak, she accused the Prime Minister of "tearing up the ministerial code" by not referring Mr Hunt to a government ombudsman. She also claimed the Chancellor George Osborne acted as a "political strategist" over the affair.
Deputy Leader of the Labour Party Harriet Harman said: "Jeremy Hunt should not be in his job. He took on responsibility for an impartial, quasi-judicial decision when he was not acting fairly, like a judge. He had already made up his mind."
Harriet Harman, the Shadow Culture Secretary, has told ITV News that the Prime Minister should never have appointed the Culture Secretary Jeremy Hunt to judge News Corp's bid for full control of BSkyB. She said that David Cameron was aware of Mr Hunt's support for the bid.
Shadow culture secretary Harriet Harman has told ITV Daybreak: "the trouble is is that what is evident is that [Jeremy Hunt] had already made up his mind that he was in favour of the [BSkyB takeover] bid."
She said she called for his resignation because "it is the job of the opposition - and it ought to be the job of the prime minister as well - to keep high standards in public office."
"It's like a judge working out his judgements in advance with one side of the case, then coming to the bench, putting a wig on a reporting it."
Harriet Harman MP, the shadow culture, media and sport secretary, has called for the resignation of her government counter-part Jeremy Hunt MP, after evidence heard at the Leveson Inquiry appeared to show his support for News Corp's bid for BSkyB.
During evidence from James Murdoch, the inquiry discussed News Corp emails that appeared to show Mr Hunt had privately expressed support.
Mr Hunt said he had "conducted this process with scrupulous fairness" and has asked Lord Justice Leveson to bring forward his appearance at the inquiry. Mr Hunt had been due to give evidence along with other politicians, including the prime minister, in May.
The deputy Labour leader Harriet Harman told ITV News that George Galloway's victory shows there is "a particular issue about that local community and the Labour party" and that there is not a "general issue" with Labour's electability.
