Jolly good fun! Queen enjoys day out at her favourite event of year Windsor Horse Show

The 92-year-old enjoyed the warmer weather in a white linen shirt, tweed skirt and a light blue cardigan as she enjoyed the first day of equestrian action in Berkshire.

The monarch has attended the prestigious event, held in Windsor Castle's private grounds, every year since it was first held in 1943 to help raise funds for the war effort.

The Queen and her husband, the Duke of Edinburgh, have competed in it for more than 30 years - with Prince Philip participating in the Carriage Driving event, which he won once in 1982. 

But on Wednesday, there was no sign of Prince Philip, who is recovering from a hip operation that he underwent earlier this year. 

In more recent years, the Queen has slowed down opting to instead watch her horses compete in the showing class competitions. 

Today she was pictured holding a pink rosette after her horse came fifth. 

And to keep from the chill in the air, one of the Queen's aides was pictured helping the monarch wrap up in a padded gilet as she watched the show from her private box. 

During the event last year, the Queen had a reason to celebrate as her horse, Barber's shop, won the Tattersalls and RoR thoroughbred.

Last year, she was joined by members of the Royal Family including her son Prince Edward and his wife Sophie as well as her grandson Peter Philips and his wife Autumn and their two children. 

This year, the Queen's grandaughter Lady Louise Windsor is thought to be competing in the competition. 

According to organisers, Royal Windsor is the only show in the UK to host international competitions in showjumping, dressage, driving and endurance. 

The five-day show is now in its 75th year. 

The appearance in the grouds of Windsor comes just over a week before the Queen's grandson Prince Harry ties the knot to Meghan Markle for the Royal Wedding on May 19 in St George's Chapel.
