The Princess Royal said that she “can’t remember a single thing” about the accident that led to a five-night stay in hospital with head injuries nearly three weeks ago.

Some bruising was visible on the Princess’s cheek as she arrived at the equine centre of Hartpury University in Gloucestershire wearing an olive green tweed suit, and navy blue hat and gloves.

The long-planned engagement was condensed from two hours to one in light of her ongoing recovery..
