Princess Anne has cancelled two royal engagements in Hampshire this week after being admitted to hospital for minor injuries.

The Princess Royal suffered minor injuries and a concussion when it is believed she was kicked by a horse.

Anne, a skilled horsewoman who competed in the 1976 Montreal Olympics, was walking on her Gloucestershire estate on Sunday evening when the incident happened, the Press Association reports.

She was due to visit Warsash Sailing Club on Wednesday as part of her role as the president of the Royal Yachting Association as it opens a newly renovated clubhouse.

Later that day, the younger sister of King Charles III was then scheduled to visit Royal Lymington Yacht Club, commemorating the 40th anniversary of the Community Sailing Programme.

However, a spokesperson for Buckingham Palace said the Princess Royal will miss this week’s engagements on doctors’ advice.

In a statement, a Palace spokesperson said: “Her Royal Highness’s engagements for the week ahead will be postponed.

“Her Royal Highness sends her apologies to any who may be inconvenienced or disappointed as a result.”

Buckingham Palace announced earlier on Monday that Princess Anne, 73, was taken to Southmead Hospital in Bristol "as a precautionary measure" following an incident on Sunday evening.

A statement from the Palace revealed she had sustained minor injuries and a concussion, and that she is expected to make a "full and swift recovery".

The statement continued: “The King has been kept closely informed and joins the whole royal family in sending his fondest love and well-wishes to the princess for a speedy recovery.”

The 73-year-old princess is understood to be awake but, due to her concussion, precise details of the incident cannot be ascertained at this stage, according to PA.

Although the exact cause of the injuries is unconfirmed, Anne’s medical team have said her head injuries are consistent with a potential impact from a horse’s head or legs.

Anne is a key member of the King’s slimmed-down working monarchy, and has played an important role as she stepped up in support of Charles amid his condition.

The princess, often dubbed the hardest-working royal, is known for her no-nonsense approach and her commitment to royal duty.
