Margaret Lynch, chief executive of Citizens Advice Scotland, has been dismissed after an investigation, the charity has confirmed.
Lynch, who was dismissed last week, had been suspended since August.
The Sunday Herald newspaper reported that there had been allegations about Lynch’s use of a company credit card and her expenses. Lynch told the newspaper she denied the allegations. CAS declined to give a reason for her departure.
Lynch led CAS for three and a half years and had previously worked at the Scottish Mediation Network, where she spent two years as director. She has also had roles at the Scottish Council for Voluntary Organisations and the Scottish Catholic International Aid Fund.
A CAS spokesman said in a statement: "CAS takes great care to ensure that public funds are spent appropriately. We can confirm that the chief executive has been the subject of an investigation, and has now been dismissed. There remains a right of appeal and therefore CAS will not provide further comment at this time."
In an open letter published in The Herald on 20 February, Dominic Notarangelo, chair of CAS, said the charity had robust financial management in place.
"Funding arrangements at CAS are the subject of considerable and robust scrutiny: internally by our management team, our audit and finance committee, and our board of trustees, and externally by our auditors and by funding organisations such as the UK and Scottish governments," the letter said.
"Our board of trustees takes great care to review and question financial management and spending decisions at CAS. In addition, our external auditors have fully approved the accounts for the year under discussion, and the UK government has made clear that it is content with our finances."
Third Sector was unable to contact Lynch for comment.
