The disgraced sprinter could face a charge of bringing the sport into disrepute when the International Associaton of Athletics Federations (IAAF) meets in Berlin this weekend to discuss comments in his book, Race Against Me.

 

A legal team from the IAAF will reveal their findings to the advisory board tomorrow afternoon and only then will a decision be made whether it should be passed to the ruling Council to discuss on Saturday and Sunday.

 

Nick Davies, the IAAF spokesman, said: "We have asked our legal experts to look at this book and whether it brings the sport into disrepute.

 

"If indeed it does then this matter will be dealt with at the Council meeting."

 

Among those in the book who come in for fierce criticism from Chambers are Sebastian Coe, the chairman of London 2012 and a vice-president of the IAAF.

 

But Chambers, who earlier this month won the 60 metres at the European Indoor Championships, is in defiant mood ahead of the meeting.

 

He said in an interview published today in Athletics Weekly: "I'm an athlete and, like it or not, I am speaking on behalf of a lot of athletes because, although they may not be as open and vocal about the situation, a lot of them realise what I went through."

 

Chambers was banned for two years in 2003 after testing positive for the banned performance-enhancing drug Tetrahydrogestrinone (THG).

 

In the book he calls himself a "walking junike" and describes how he evaded a series of drugs tests over a two-year period.

 

Chambers said: "I stress that I can only talk about what the situation was then.

 

"I don't know what the current situation is now.

 

"I'm hoping that it's in a better position, especially coming up to [London] 2012."

 

The IAAF could demand in full the $120,000 (£82,440) he owes them in prize and appearance money he won at a time he admitted he was on drugs before they allow him to compete again.

 

Under an agreement struck in 2006, he is currently repaying the money as and when he can.

 

The Londoner is deep in financial problems because he is banned from most of Europe's top meetings.

 

Chambers said: "I realise I am not everybody's cup of tea and, to be honest, I've come to realise that when I talk it gets a negative reaction, but it's okay when others speak badly about me.

 

"I try not to be bitter about it and, I have got older, I understand the nature of sport and life.

 

"I've been called every name under the sun,but I take it all with a pinch of salt.

 

"On one side I expect some negatives, but I also expect some positives.

 

"As a man, I believe you have to stand up for what you believe is right and that's what I am doing."

 

If any further disciplinary action is taken against Chambers it could lead to fresh legal action against the authorities.

 

His legal team claim that he cannot be given another suspension for something he has already been found guilty of.

 

Davies said: "The truth is he has been punished.

 

"So he is eligible to compete.

 

"But the IAAF has been clear about this.

 

"We wanted four-year bans."
