Children's charities Sparks and Dreams Come True will retain Princess Michael of Kent as their patron, despite reports of her racist remarks in New York last week.
The reports alleged that she told a group of black New Yorkers to "go back to the colonies", while dining in Manhattan.
Immediately after the story broke last week, Sparks cancelled a reception thanking fundraiser Jane Tomlinson for her efforts because organisers were convinced the media would have seized the chance to question the Princess.
But Paul Connew, head of communications at Sparks, said the charity backed her because "she rejects the reported interpretation of what she said".
He vowed that the annual polo day bearing the Princess' name would continue on 3 July, because there has been "no indication that it will suffer".
D'Arcy Myers, chief executive of Dreams Come True, said: "We highly value our patron's support and won't comment on any alleged remarks attributed to her."
Simon Astaire, the Princess' official spokesman, said: "The Princess will not be resigning any of her charitable roles. She denies that she made any racist comment and doesn't consider herself a racist."
