Sugar tells Allsopp 'you need to diet'

Alan Sugar stepped up his online feud with TV presenter Kirstie Allsopp today by telling her to lose weight.

The straight-talking Apprentice guru said she should consider "a diet" after he saw a clip of the Channel 4 presenter.

The exchange is the latest in a lengthy to-and-fro between the pair which erupted on Twitter.

The latest episode began when Sugar reminded his online followers to observe the two-minute silence yesterday.

Another tweet followed shortly afterward which he blamed on a technical glitch.

But Allsopp spotted the remark and wrote: "Using the 2 minutes silence to plug your book? That's unforgivable by anyones standards!"

Sugar reiterated his claim that there had been a technical problem and responded that having seen a "clip of her TV show, she really needs to think about a diet".

He also drew attention to an expletive on Allsopp's Twitter account and asked: "Did you pick that language up at Roedean Darling lovie?"

Problems between the pair erupted a month ago when they began a slanging match on the social networking site. They had briefly worked together on a celebrity version of The Apprentice.

Last month she wrote of Sugar: "I worked with him on Sport Relief Does The Apprentice. His behaviour was shockingly uncharitable."

She later said: "There r words I don't use, but when it comes to Sugar & his treatment of the staff & crew involved... in any other work place he'd be Fired!!"

He said Allsopp was "a lying cow" and that she was the "worst contestant on celeb apprentice ever".

Sugar has not just reserved his insults for celebrities on Twitter. He told one user: "Why dont you shut up and get a life, by the way you look like Susan Boyle."
