All Scottish councils "must learn from the weaknesses" that allowed a council employee’s £1.1 million fraud go undetected over 17 years, the public spending watchdog for local government has said.

Between 2006 and 2023, Michael Paterson, who was employed as a council tax and recovery team leader for Aberdeen City Council, transferred 655 council tax refund payments totalling £1.109m into his own bank account.

The fraud was identified by the council in September 2023. Paterson was charged by Police Scotland in December that year and dismissed by the council. He received a four-year prison sentence at the High Court in Edinburgh in July 2024.

The council said it expects to be able to recover the lost funds, with no loss to the taxpayers whose accounts were affected.

However, in a new report published on Thursday, the Accounts Commission said it is concerned that whilst the council had a system of controls in place, "these were not adhered to and lacked scrutiny".
