The Queen's love of horses

One thing has remained a constant throughout the Queen's 90 years - her love of horses.

She has owned and bred horses during her reign and her passion for the animal is showing no signs of fading.

Her Majesty is therefore likely to enjoy her 90th birthday celebration which will celebrate her "love" of horses in front of a sell-out crowd at Windsor Castle on Sunday.
