Princess Anne, King Charles’ younger sister, is in hospital after suffering a head injury on Sunday, Buckingham Palace said, adding the royal was expected to make a full recovery from the incident which was believed to have involved a horse.

The palace said on Monday that the 73-year-old, the only daughter of the late Queen Elizabeth, had suffered minor injuries and a concussion following the incident, and was now recovering at Southmead Hospital in Bristol, west England.

The princess had been walking in the grounds of Gatcombe Park estate where her home is located when she suffered minor injuries to her head, a royal source said.

The source said there were horses in the vicinity and her medical team said the head injuries were consistent with impact from a horse’s head or legs.

Her husband, Tim Laurence, accompanied Anne to hospital and her two children, Zara Tindall and Peter Phillips, were also on the estate at the time.

The princess is expected to return home this week, but her upcoming engagements have been postponed and Anne will not fly to Canada as planned at the end of the week, the source said.

However, the official state visit of Japanese Emperor Naruhito and his wife, hosted by King Charles, will go ahead as planned, starting on Tuesday.
