The London trader accused of spoofing the US financial markets will be extradited to stand trial in the States after losing his final appeal.

Navinder Sarao, a 37-year-old from Hounslow, has been fighting the US authorities’ bid to extradite him since he was arrested at his home in April 2015.

He has been charged with 22 offences that come with a maximum sentence of 380 years in total. His trading strategies, run from his bedroom in his parents’ home, generated $40m (£32m) in profits, prosecutors allege.
