The Princess of Wales is being treated in hospital after undergoing surgery on Tuesday and is expected to remain there for up to two weeks.
Catherine, 42, was admitted to the London Clinic in Marylebone for the planned abdominal procedure, with no further details being given.
She has not been seen in public since she attended the Royal family’s Christmas Day church service in Sandringham with her children.
The palace said she will not be sharing her private medical information in the public domain.
