It is normally a place to swap recipes and discuss the perfect poached egg, but TV cook Delia Smith’s website has been hijacked by simmering soccer supporters.

The veteran culinary writer has been forced to wipe clean the community forum page of Delia Online after angry Norwich City fans used it to air their grievances against her, as chairman of their club.

One, using the name ‘Delia Mugabe’, went as far as branding her an ‘old trout’.

The Norwich fans are furious that Delia, 67, and her husband, Michael Wynn-Jones, the club’s controlling shareholders for 12 years, have rejected a £20 million takeover offer by Peter Cullum.

The millionaire businessman had promised to invest in new players but Delia, herself worth an estimated £22 million, turned him down.

‘Delia Mugabe’ wrote: ‘Delia, you old trout. Stick to what you know and leave the football to the people that know best.’

The disaffected fan also made reference to the barrage of criticism that Delia faced earlier this year from other celebrity chefs over her book How To Cheat At Cooking, which offered people the chance to make their own dishes in a fraction of the time but using ingredients such as tinned mince and frozen mashed potato.

He wrote: ‘A title for your next book – how about How To Cheat Norwich Fans Out Of The Club That Is Rightfully Theirs?’
