Police are investigating how nude photos believed to be of British prime minister David Cameron's nanny were uploaded onto the internet.
The unidentified woman, who takes care of Cameron's children, said the photos could have come from a vengeful former lover, The Sun in the UK reported.
She reportedly said she had not posed nude for pictures for years.
The woman is pictured next to a profile advertising live sex shows, and showed her in "overtly sexual poses".
“She’s horrified these profiles have come to light and is mystified at how they got there,” a source told The Sun.
“She insists it was nothing to do with her and must be down to one of her ex-boyfriends.
“She realises that the worst scenario could have been if someone had used the stuff posted on there to try to blackmail her.”
Police are now investigating the claim after confirming they had received a complaint from the woman, The Sun reported.
The nanny is close to the Cameron family, the source said.
"She enjoys working with them, particularly the children, who she’s great with," the source said.
"She gets on really well with Samantha. She says she is lovely, down to earth and a good laugh."
