Two jailed Capital+Merchant directors have failed in their "strawman" bid to take their case to the Supreme Court.
Wayne Douglas and Neal Nicholls, the founding directors and beneficial owners of Capital+Merchant, were found guilty in July last year of three charges of theft by a person in a special relationship.
In a case brought by the Serious Fraud Office, both men were each jailed for seven and a half years, the longest sentences given to failed finance companies bosses to date.
Former director and chief executive Owen Tallentire was also found guilty of two charges in this case and sentenced to five years in jail.
The trio then attempted to overturn their convictions and sentences in the Court of Appeal but this was rejected in December.
