Sarah Ferguson has claimed the invitations for King Charles III's upcoming coronation "haven't gone out yet".

While speaking to Extra TV for an interview published on Monday, the Duchess of York was asked whether she was invited to the upcoming coronation scheduled for King Charles III on 6 May.

"The invitations haven't gone out yet, so I don't know if I'm going to be there because, you know, who wants me around," she joked. "I was thinking that I would open a little tearoom, a portable tearoom at the bottom of the drive."

The 63-year-old was married to the King's brother Prince Andrew between 1986 and 1996 and they share two daughters - Princess Beatrice and Princess Eugenie.

Her comments come shortly after a spokesperson for Prince Harry and Meghan, Duchess of Sussex confirmed they had been invited to the historic event. Their representative did not disclose if they will attend.

Elsewhere in the interview, Ferguson promoted her novel A Most Intriguing Lady, which she said was inspired by research she conducted on her great-great-aunt Lady Margaret Montagu Douglas Scott.

"I sort of like the feeling that I've brought her back to life, you see, and that's in my book," she shared. "During the day... she's very much a lady, and at night, she might have to go in disguise and do strange things at night. She's a sleuth."
