Companies deserted charities they traditionally supported in the aftermath of the Asian tsunami to support those affected by the disaster, according to research by the Institute of Fundraising.
The report, released six months on from the disaster, analysed how the tsunami appeal has affected fundraising in the UK. It showed that 36.8 per cent of the charities asked have seen a decrease in their income from corporate donations.
Institute chief executive Lindsay Boswell said: "This is hugely disappointing when you consider that a large proportion of the British public dug deep in their pockets at a time when they could least afford it - in the immediate aftermath of Christmas."
Despite the figures, the institute's research showed that 73.6 per cent of the 132 respondents, representing a total of £627m in fundraising income, thought the long-term impact would be positive. A quarter of those surveyed believed the impact would be negative, and 50 per cent thought it would raise the profile of the sector.
The Disasters Emergency Committee revealed last week that the £400m given to the tsunami appeal was eight times the amount raised for Kosovo in 1999, the previous record.
