The Society of St. Vincent de Paul has blamed recent controversies on charity donations for the 25 per cent drop in its donation intake this Christmas.
The charity believes the revelations of salary top-ups from charity donations at the Central Remedial Clinic has damaged the charity sector as a whole.
''There's no doubt the CRC controversy has had an impact,'' said SVP spokesperson Jim Walsh.
The national figure for donations has dropped between 20 to 25 per cent across the country.
''It's a shame that the actions of a few people has impacted on so many vulnerable people this Christmas,'' he told independent.ie.
Mr Walsh insisted that the number of people donating has not dropped, it is the value of each donation that has decreased.
''The generosity of the Irish people is still brilliant, but the amount of each donation has dropped,'' he said.
SVP volunteers are said to be worried that they will not be able to deliver the level of support expected this Christmas with fewer donations.
He said it is important that the public know that any donations given to their local SVP stays local and assists struggling families in that community.
''It's important to say that SVP donations stay in the area and goes to those who are in need,'' he said.
Mr Walsh acknowledged that another factor was that families were under pressure this year and struggling to cope themselves this Christmas.
The charity is hoping that more donations will flood in in the run up to Christmas.
During the festive season, SVP aims to assist more than 150,000 people with food, fuel and toys.
