Alastair Campbell, who is heavily criticised in Paul Dacre's article in the Guardian, has hit back at the Daily Mail's Editor on Twitter:
Make your mind up Dacre. Either I'm BBC's destroyer (your rag passim) or co-conspirator against your lovely paper. Can't be both #bunker
Daily Mail editor-in-chief Paul Dacre has a written a comment piece in the Guardian in which he seeks to refute criticism of his newspaper.
The article comes following protests about a Daily Mail article on the Labour leader's father Ralph Miliband.
Mr Dacre wrote: "Yes, the Mail is happy to accept that in his personal life, Ralph Miliband was, as described by his son, a decent and kindly man – although we won't withdraw our view that he supported an ideology that caused untold misery in the world.
"Yes, we accept that he cherished this country's traditions of tolerance and freedom – while, in a troubling paradox typical of the left, detesting the very institutions and political system that made those traditions possible.
"And yes, the headline was controversial – but popular newspapers have a long tradition of using provocative headlines to grab readers' attention. In isolation that headline may indeed seem over the top, but read in conjunction with the article we believed it was justifiable."
The full article was published on The Guardian website.
A Facebook page calls for "all the people hated by the Daily Mail" to attend a protest outside the newspaper's headquarters on Sunday. It reads:
On Sunday, all the people hated by the Daily Mail - that's pretty all of us - are going to turn up at their headquarters, loud and proud about who we are. If you're a woman, a Muslim, LGBT, a nurse, a socialist, a trade union rep, disabled person or just someone who doesn't like hatred being pumped into public life every day, turn up.
More than 1,200 people have pledged to attend, and a further 460 said they might turn up.
More than 1,200 people have pledged to hold a protest outside the headquarters of the Daily Mail newspaper on Sunday.
A Facebook event set up by the protest group People's Assembly says the demonstration was sparked by a row over an article accusing Ed Miliband's father of "hating Britain".
It invites "all the people hated by the Daily Mail" to gather outside the newspaper's headquarters in West London at noon for an "upbeat, carnival-type protest".
