Jamie Oliver has re-ignited his feud with Gordon Ramsay accusing him of being "deeply jealous" of his success.

The 39-year-old television chef lashed out at his rival after he was criticised for not attending the opening of a new branch of Jamie's Italian in Hong Kong.

Ramsay, who opened his own kitchens in the former British colony, said his fellow Briton could "at least turn up."

Oliver said: "Gordon will do anything to try and take the piss out of me because he is deeply jealous and can't quite work out why I do what I do and why he can't do that.

"He is too busy shouting and screaming and making our industry look like a bunch of shouters and screamers."

Oliver and his wife Jules saw their fortune leap £90m to in excess of £240m with their restaurant chains, TV appearances and her childrenswear range.

Meanwhile Ramsay, who once saw his then £70m fortune crash by half after a split with his mentor and wife's father, Chris Hutcheson, has come back to well over £100m with a worldwide chain.

Oliver said in an Australian interview, that their rivalry ben extended to the bookshelves his 15th book Save With Jamie shot to the top of the UK bestsellers list, bringing his career sales to just over 37 million.

By contrast Ramsay's whose 21 titles have sold an estimated three million copies.

"I think that really, really annoys him.

"Book sales are about having a deep trusted relationship with the public. I really write my books. I don't just turn up for the front cover. I write every word, every letter and I oversee every bit of design."
