The former chief executive of the Scottish National Party bought a motorhome and robotic lawnmower with party donations, a court has heard.
The High Court in Edinburgh heard Peter Murrell embezzled £400,310.65 from the SNP's principal bank account, "over which he had control".
Sentencing of the 61-year-old, who is former Scotland first minister Nicola Sturgeon's ex-husband, is due to take place later in June.
Reading out the prosecution narrative this morning, Alan Cameron KC said the funds in that account came mainly from "membership fees and donations paid by party members and other donors and legacies".
He said Murrell falsified accounting records and created fake invoices in a bid to cover up his wrongdoing as he racked up purchases that included a £124,550 motorhome and thousands of pounds of luxury stationery.
He told the court one of the vehicles included a Volkswagen Golf car, which was later sold and the proceeds used towards buying a Jaguar I-Pace worth more than £81,000.
Mr Cameron said a false invoice was created for this, submitting the claim as "stage payment".
He also discussed the purchase of a motorhome by Murrell, which was worth £124,550.
When police seized the vehicle from his mother's house, the odometer showed it had only been driven for four miles.
He said it was decribed as a "van rather than a motorhome" when the invoice was filed.
On Monday last week, Murrell admitted embezzling £400,310.65 from the SNP between August 2010 and October 2022.
Court papers revealed a lengthy list of items he bought with the embezzled money, including a space telescope, DVDs, a home library ladder worth more than £900 and a coffee machine worth nearly £3,232.
Murrell's guilty plea has led to intense scrutiny for his former wife Ms Sturgeon, who has denied knowing of his crimes - saying she was "deceived, misled and betrayed".
The former SNP leader said she has been "completely exonerated" after a "two-year-long, very forensic police investigation" which saw police officers search the home she and Murrell had shared.
Ms Sturgeon was arrested and questioned as part of the police investigation into the SNP's finances, which was known as Operation Branchform, but Police Scotland confirmed she would face no action.
