Dwain Chambers' agent has blogged for The Huffington Post UK to air his grievances over the treatment of his client.
Chambers tested positive for performance-enhancing drugs in 2003 and received a lifetime ban from competing at the Olympics.
Starting on Monday, the 33-year-old will contest a British Olympic Association by-law that excludes drug cheats from selection, and Siza Agha, a lawyer who doubles up as Chambers' agent, is calling on the British public to support their fallen athlete.
"He admitted his guilt, he assisted the authorities, but he does not have the support of his own Federation UKA and indeed the BOA.
"He has to prepare for Major Championships away from the premium events and the phrase 'drugs cheat' still punctuates press reports, despite the unhappy chapter happening the best part of a decade ago."
Agha urges the British public to get behind the athlete, who aspires to compete at London 2012. You can read Siza Agha's blog here.
