The 'flash crash' trader accused of triggering the 2010 Wall Street crash is to be extradited to the United States.
It comes after a judge at Westminster Magistrates' Court ruled that British financial trader Navinder Singh Sarao, 37, can be extradited to face trial in the US.
Sarao faces 22 charges which carry sentences totalling a maximum of 380 years.
American authorities claim the Briton made $875,000 dollars on May 6 2010, the day of the crash, part of illegal earnings of more than 40 million dollars (£26 million) in five years.
Lawyers for Sarao, who argued his actions did not constitute a crime, said outside court that they will lodge an appeal once Home Secretary Theresa May makes her final decision in the case.
