Dubliner Pat McQuaid has failed to secure the nomination of Cycling Ireland to run for a third term as president of the Union Cycliste Internationale (UCI).
The country’s clubs gathered at an emergency general meeting of Cycling Ireland in the Red Cow hotel where Mr McQuaid lost the crucial vote 91 to 74.
McQuaid is being challenged by British Cycling chief Brian Cookson for the leadership of the UCI and he needed the backing of his home federation for his name to be on the ballot paper when the UCI's members vote in September.
The UCI was implicated in the Lance Armstrong doping scandal by the US Anti-Doping Agency and was criticised by the World Anti-Doping Agency when an independent panel it established to examine its own alleged complicity was disbanded before it could report that led to strong criticism of McQuaid.
The defeated motion, posted on Cycling Ireland's official website, read: "That Mr Pat McQuaid be and is hereby nominated by Cycling Ireland to stand as a candidate for the Presidency of the UCI at the 2013 UCI Congress and that the said nomination be executed and submitted forthwith by the Board of this Company."
The Dubliner has been in charge of cycling's international governing body for eight years but today's result saw his chances of winning re-election in September suffer a serious blow despite Irish cyclists Stephen Roche and Sean Kelly speaking in his favour at the hour-long meeting.
The EGM was convened after Cycling Ireland's original decision to nominate McQuaid for a third term in April was overturned on a technicality. There appear to be concerns over his perceived leadership failings, including the Lance Armstrong doping scandal.
He was also criticised by the World Anti-Doping Agency (WADA) when an independent panel the UCI had established to examine its own alleged complicity was disbanded.
McQuaid's hopes of receiving a nomination to oppose British Cycling president Brian Cookson now rest with Swiss Cycling, who announced it had nominated the Irishman last month due to his long-term residency in Aigle.
However, that decision is currently the subject of a legal challenge from three of its members: Kurt Buergi, Mattia Galli and Patrick Calcagni. Swiss Cycling is preparing to convene to address the issue.
