NNA - 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.

"Her royal highness is recovering well, is in a comfortable condition and is being kept in hospital as a precautionary measure for further observation," a Buckingham Palace spokesperson said.

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. -- Reuters
