Ngozi Fulani, 61, has revealed how she was quizzed by Lady Susan Hussey, 83, at the palace last week.
The British-born boss of Sistah Space – a charity for Afro-Caribbean victims of domestic abuse – said the lady-in-waiting kept asking her: 'Where are you really from?'.
According to a transcript Ms Fulani posted online, Lady Hussey asked where she came from, to which she replied that her charity was based in Hackney, North-East London.
Ngozi Fulani, 61, (pictured on Good Morning Britain on Thursday) has revealed how she was quizzed by Lady Susan Hussey, 83, at the palace last week.
Lady Susan (pictured), who had served the late Queen for six decades, stepped down from her honorary role 'with immediate effect' amid a furious outcry after Ms Fulani revealed the exchange on Twitter.
A stunned Ms Fulani replied: 'My people' lady, what is this?' She eventually said she was of Caribbean descent and African origin, to which Lady Hussey apparently replied: 'I knew we'd get there in the end, you're Caribbean!'.
Palace sources said the King and Camilla will meet the Sistah Space chief executive at the palace.
Now plans are under way for Charles and Camilla (pictured) to meet Ms Fulani so that they can address what happened at the event and the issues involved
