Lord Alan Sugar has called for Daily Mail editor Paul Dacre to resign over the paper's treatment of Labour leader Ed Miliband.
Speaking to Channel 4 News, the business magnate also urged brands to withdraw their advertising from the newspaper.
And as the row between the Mail and Miliband intensified, former Labour spin doctor Alistair Campbell last night tweeted Dacre’s home address after spending the day making various media appearances to denounce the newspaper and its editor.
Sugar said the shareholders of the Daily Mail should demand Dacre’s resignation.
“There is a special ilk of people that work at the Daily Mail, nasty, nasty people and it starts at the top with this Paul Dacre guy who has gone too far this time,” he said.
“I think the shareholders of the Daily Mail group have got to demand his resignation.
“He is a tyrant and a he needs to be expelled from the newspaper.”
He said that Daily Mail shareholders would “start to get a bit tetchy” if advertisers withdrew their placements in the newspaper.
“Certainly if I was an advertiser I would think twice before placing any money in that newspaper… and I would urge them [advertisers] just as a punishment to them, to actually pull their advertising, next week and the week after that,” he said.
