This is the moment an army pony misbehaves in front of a royal visitor. 

The Welsh mountain pony, Trooper 'Longface' Emrys Jones, was promoted from Lance Corporal to Corporal during the visit from the Princess of Wales. 

Princess Kate was touring the home of the 1st The Queen’s Dragoon Guards (QDG) at Swanton Morley, near Dereham, for the first time since being appointed its Colonel-in-Chief by the King in August.

The Regiment chose a Welsh mountain pony to keep in touch with their Welsh heritage and the tradition of the Welsh Cavalry charging into battle on horseback. 

Princess Kate tried her hand at flying a drone and even drove a seven-tonne Jackal vehicle around the grounds during her visit to the barracks.
