The day was unsuccessful for the late Queen's granddaughter, 43, who fell from her horse Class Affair in the cross-country event, which knocked her from the competition. Thankfully, the mum-of-three was unharmed, and despite the disappointment, the Tindall kids enjoyed a day out.
The onlooker told Best Quality Designer Handbag that Mike kept a close eye on his son during their day out and handled his cheeky behaviour with admiration.
Peter Phillips' partner Harriet Sperling was quick to rescue Lucas, saving him from hitting the floor. The onlooker told HELLO! that the 44-year-old interacted comfortably with the wider family.
