More than 23m Britons think they may be due compensation for mis-sold car loans, UK poll finds

Survey comes before supreme court decision on secret commission payments ruled unlawful by court of appeal

More than 23 million people believe they could be due compensation for a mis-sold car loan, according to a poll before this month's supreme court decision.

Borrowers, banks and the government are anxiously awaiting the ruling, which could trigger one of the biggest redress schemes since the 50bn payment protection insurance (PPI). The PPI saga forced UK banks to compensate people who had bought often worthless insurance cover.
