England football fan Garry Mann will be extradited to Portugal to serve a two-year jail sentence for hooliganism.
The former Kent firefighter, 52, will travel from London's Heathrow Airport to Lisbon and then be transferred to an as-yet undisclosed prison.
He was convicted over a riot during the Euro 2004 tournament but says he did not have a fair trial.
Mr Mann's lawyers failed in a last-ditch attempt to secure a judicial review at the High Court last week.
Mr Mann, a father of six from Faversham, said he has been caught up in extradition laws intended for terrorists and warned others will follow him.
He said: "I have been let down by the politicians that agreed to the UK's rigid extradition laws and the European arrest warrant and by the judges who no longer seem willing to stand up for justice.
"This was supposed to have been for terrorists implemented after the 9/11 attack but, for some reason, I have been caught in its net. I am not the first victim of this system and, until it's reformed, I won't be the last."
Jago Russell, of Fair Trials International, said Mr Mann's trial was a "travesty of justice" and the decision to extradite him was an "outrage".
A Birmingham City supporter, he was drinking with friends in a bar in Albufeira when a riot involving football fans began in a nearby street.
Mann was arrested, tried and convicted within 48 hours. His lawyers said he was only granted five minutes with a lawyer before trial, could not understand the proceedings and did not know what charge he faced until after he was convicted.
