Tom Hayes, the Libor trader sentenced to more than a decade in prison for his attempts to manipulate the benchmark, is launching an appeal.
The former UBS and Citigroup trader, nicknamed Rain Main by his colleagues, believes he was treated unfairly in court because of his diagnosis with Asperger’s syndrome, a form of autism.
