One of the Queen's racing trainers has recalled the moment her winning celebration sparked security fears.
Amid the plethora of tributes this week, Nicky Henderson shared one of his favourite memories of Britain’s longest-reigning monarch.
Horse racing's biggest supporter, the Queen had many thoroughbreds in training at his Lambourn stables during her 70-year reign. The best of them, Barbers Shop, ran in the 2009 Gold Cup and placed in that year's King George VI Chase at Kempton.
