Zara Tindall visits mum, Princess Anne, as the Princess Royal remains in hospital after horse incident

Princess Anne had a visit in hospital from her daughter, Zara Tindall, on Wednesday.

The Princess Royal remains in Southmead Hospital, days after an incident with a horse on her Gloucestershire estate of Gatcombe Park.

Her husband Sir Tim Laurence told media camped outside the Bristol facility on Wednesday, the 73-year-old is "recovering slowly" and will be discharged "when she is ready".

While Buckingham Palace had previously said they hoped to see Princess Anne out of hospital later this week, Laurence, 69, declined to speculate on a timeframe.

"She'll be out when she's ready," the Vice Admiral said in his progress report.

Laurence, who sweetly was seen bringing his wife treats from home in a cooler bag on Tuesday, returned to spend a few hours by Princess Anne's side on Wednesday.

Tindall was also seen visiting her mum, looking chic in the hot weather by wearing cut off denim shorts with a matching denim-style shirt.

This was paired with sneakers and a cross body bag in various shades of white.

The Princess Royal - the daughter of the late Queen Elizabeth and Prince Philip - was taken to hospital on Sunday, after sustaining minor head injuries and a concussion while out for a walk on her estate.

King Charles's sister has cancelled all of her royal engagements for the week, which included supporting her brother during the Japanese emperor and empress's state visit to the UK.

The Princess Royal was also due to travel to Canada this week but has postponed that trip on doctor's advice.
