More than 1,000 people cancelled their regular donations to Oxfam over the weekend as more claims about a Sexual Misconduct Scandal emerged.
The number is far above the average cancellation rate of 600 per month.
The charity is at the centre of allegations that staff working for Oxfam in Haiti and other countries paid vulnerable people for sex.
A spokesperson for Oxfam said: "We are grateful for the support of people during this difficult time for Oxfam, some of whom have expressed that they are deeply saddened by the repercussions of the appalling actions of a few - they are determined that the millions of people that Oxfam helps worldwide don't suffer as a result."
Oxfam said it had received 78 single gifts on Tuesday, the highest number since 1 January.
