Royal commentator Michael Cole has claimed that we "may never know" what happened to Princess Anne after she suffered mild head injuries and was rushed to hospital earlier this month.
This comes as the Princess Royal was seen for the first time since the incident that involved a horse and left her in hospital for five days.
Princess Anne visited the Riding for the Disabled Association (RDA) National Championships at Hartpury University and Hartpury College in Gloucester earlier today.
The RDA is celebrating its 55th anniversary this year and Her Royal Highness has been the Patron of the RDA since November 1971.

GettySpeaking to GB News, a former royal reporter for the BBC Michael Cole said: "It's a gentle beginning, back doing her role.
"Of course, she is famously the most hard-working member of the Royal Family, 168 engagements last year, and I'm quite sure she'll be back in the swing of it.
LATEST DEVELOPMENTS:
"Of course, we still don't know the details of what actually happened when she met this horse and what happened.
"Apparently she has no memory of it. So maybe it will remain a mystery between her and the horse."
Following the incident, Buckingham Palace confirmed that on doctor’s advice, Anne's engagements would be cancelled until further notice.
Anne was unable to carry out a scheduled trip to Canada following the injuries.

Canada's Governor General read a message from the Princess in her absence at a memorial ceremony.
Anne said: "It is with deep regret that I am unable to be with you today, as you commemorate the brave efforts and sacrifices of the members of the Newfoundland Regiment who went into battle on the first day of the Somme.
"I have fond memories of joining you in 2016, on the 99th occasion that the people of this Island commemorated the Battle of Beaumont Hamel, and I am deeply saddened that I’m unable to join you again, and I send you my warmest best wishes on this special day of commemoration."
In June, Anne's husband, Vice Admiral Sir Timothy Laurence, said that his wife was "recovering slowly" following the accident, and went on to praise the medical staff who looked after her at Southmead Hospital.
