A former Barclays Plc trader lost an attempt to have an appeals court throw out his conviction for Libor-rigging, as judges rejected complaints about a key witness for the prosecution.
Alex Pabon’s request was thrown out by the Court of Appeal in London Tuesday, months after he had been released from prison. The ruling makes it less likely that similar convictions would be overturned, securing those of other bankers caught up in the Libor scandal, including former UBS Group AG trader Tom Hayes.
