Ian Blackford has furiously denied it was his responsibility to inform House of Commons authorities about the resignation of the SNP's financial auditors.
The party's former leader at Westminster clashed with a reporter when asked why parliamentary officials were not informed when an accountancy firm ended its business relationship with the Nationalists.
The SNP must have a new auditing team in place by the end of next month or risk losing £1.2million in Short money - public funding given to all opposition parties in Westminster.
