The Dwain Chambers saga continues to run and run, with the former drugs cheat declaring that he intends to compete at the Olympic Games in Beijing. Having dished the dirt on himself during a meeting at UK Sport, the disgraced sprinter will focus on securing a place on the biggest stage in sport.

A carefully worded statement from Nick Collins, his lawyer, stopped short of saying that Chambers would mount a legal challenge to the British Olympic Association (BOA) bylaw that bans all doping offenders for life. However, that will be forthcoming now that Carl Myerscough, the shot putter who tested positive for steroids in 1999, has performed an about-turn and decided that he will not be taking the matter to the High Court.

“We can confirm that Dwain Chambers will be taking proceedings to secure his eligibility/participation in the Olympic and national trials in Birmingham from July 11 to 13,” the statement read. That will not be a problem. UK Athletics (UKA) will send an invitation to Chambers if he secures the qualifying standard of 10.85sec, which he will probably do for Birchfield Harriers. The mud will fly after that.

UKA clashed with Chambers, who completed a two-year doping ban in 2005, over his eligibility for the World Indoor Championships in Valencia in March. UKA eventually accepted it could not bar Chambers from the trials and when he won, it faced the threat of legal action if it failed to pick him for the championships. It is more confident of fending off any legal threats over the Olympic trials. Unlike the world indoors event, the Olympic selection criteria do not have a first-past-the-post clause, giving UKA more discretionary powers to omit Chambers, even if he wins the trials.

Collins said last night: “It is a case of taking things one step at a time. First he has to get to the trials. Then he has to win. Then we will see.”

If Chambers waits until after the trials to mount a legal challenge, it will throw the selection for the Games into chaos. The BOA has the final say on who goes to Beijing, with UKA sending a list of nominations by July 19, six days after the end of the trials. Collins hinted that a legal challenge could be mounted after that date.

Lord Moynihan, the BOA chairman, has vowed to defend bylaw 25, adding: “There will be no room for cheats in the British team as long as I am involved with the BOA.”

Chambers spent two hours yesterday at UK Sport yesterday explaining the contents of the letter sent by Victor Conte, his former supplier, and detailing his drug use. John Scott, the director of Drug-Free Sport, UK Sport's anti-doping arm, said: “Through the letter ... he has provided a detailed account of his doping programme, which highlights the level of sophistication that goes into these systematic regimes.

“It is through this sort of information that we are able to better understand both the mindset of why athletes choose that path and the network that sits behind them. It is these networks of manufacture, trafficking and supply that we need to be able to tap into if we are to get to the heart of doping in sport.”

Scott had previously urged Chambers to name those complicit in his doping, but refused to divulge whether he had done so.
