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.
Jeremy Hunt has faced stinging criticism over his performance at the Leveson Inquiry, adding further pressure on the Culture Secretary.
