Miliband said he was appalled the paper had repeated the lie that his father hated Britain, saying: "I'm not willing to let my father's good name be besmirched and undermined in the way that the Daily Mail are doing. It is about right and wrong. It is about how the way we conduct political debate in this country."
A spokesman for the paper said: "We ask fair-minded people to read our editorial. For what this episode confirms is that you cannot allow politicians anywhere near regulating the press." But Miliband said: "This is not about regulation. It is about right and wrong."
He received support from Westminster, with the Lib Dem leader Nick Clegg saying that politics "should be about playing the ball, not the man, certainly not the man's family". Prime Minister David Cameron also backed Miliband, saying: "If anyone had a go at my father, I would want to respond very vigorously. There's not a day goes by that you don't think about your dad and all that he meant to you, so I completely understand why Ed would want to get his own point of view across."
In the original article the writer Geoffrey Levy examined the political beliefs of the Marxist academic and how they influenced his two sons. The paper quoted the 17-year-old Ralph writing in his diary that the Englishman is a "rabid nationalist" and "you sometimes want them almost to lose [the war] to show them how things are".
But Miliband said politics did not justify character assassination of his father, who joined the Royal Navy and fought in World War II after arriving in Britain from Belgium. Miliband has frequently referred to his father in speeches and how his values and experiences shaped him.
He wrote: "Like most refugees, the security of our country was really important to him. And like some refugees, he owed his life to it. So my dad loved Britain, he served Britain, and he taught both [brother] David and me to do the same."
