Last weekend the EBU general assembly passed a motion that decreed the LBF would be thrown out of the European organisation if they continued to back the fight.

But despite this threat, the LBF last night voted in favour of backing the bout by eight votes to four at a special general meeting in Luxembourg.

A statement released by Frank Warren Promotions read: "Therefore the LBF is backing the show along with the World Boxing Organisation (WBO) and the World Boxing Association (WBA), whose' International and Intercontinental titles will be contested, and the promotion will definitely go ahead."

Last night's events are the latest instalment in what has been a controversial build-up to the fight between the two Londoners, who caused outrage in February when they brawled at a press conference that followed Chisora's defeat to Vitali Klitschko.

The British Boxing Board of Control (BBBofC) threatened to expel all those involved in the July 14 fight without a hearing, although they softened their stance last weekend by claiming anyone charged would be able to answer their case.

Warren, who manages Chisora, has said he intends to issue legal proceedings against the BBBofC.

WBA, IBF and WBO heavyweight champion Wladimir Klitschko branded the bout a "freak show", but Warren insists the fight is legal and is adamant that Chisora should be allowed to take on Haye as he has not been able to box since February.

Haye has not fought since an embarrassing defeat to the younger Klitschko brother last summer - a loss he partly blamed on a broken little toe.

Chisora goaded his 31-year-old opponent last Sunday when he wore a t-shirt that had the words "Ain't toe stopping us now" emblazoned across the middle of it during a public workout in London.

Haye and Chisora exchanged insults over a wire fence during a press conference to promote the fight at West Ham's ground in east London last month and it is clear there is no love lost between the pair.

Haye today mocked his Zimbabwe-born opponent, telling West Ham TV: "Dereck talks a lot but I'm not sure he actually understands boxing.

"He's got a good chin but I certainly don't think he has enough to beat me.

"I believe Chisora is going to come out slinging bombs and that will suit me perfectly.

"It's going to be entertaining. You'll see some stuff from me that you haven't seen for a while. A new improved Hayemaker."

Chisora, who beat Danny Williams at Upton Park two years ago, is looking forward to proving Haye wrong.

He said: "David and I have some unfinished business but after July 14 it will be done and I will be the happy one.

"This is the second time I've fought here I'm looking forward to this one. It has a great atmosphere. I really like it.

"I'm ready for it and I can't wait to get in that ring."
