The collapse of an energy company set up by Nottingham City Council has left more than £50m of bills unpaid, a report on its final liquidation has found.
The winding-up of Robin Hood Energy has been completed five years after it went into administration.
It found there were 347 claims of owed money from individuals and companies amounting to £67.1m, with only £13.7m of the claims paid out.
The city council has been approached for comment, the Local Democracy Reporting Service said.
