Royal fans all say the same thing as horse spotted without a rider at Queen’s Trooping the Colour

KEEN royal fans are all saying the same thing after spotting a lone horse without a rider at Trooping the Colour.

Eagle-eyed viewers spotted the horse out of formation and without an accompanying rider during the Queen's Platinum Jubilee celebrations.

The stunning spectacle kicked off the four-day celebrations for the Queen - who celebrates a sensational 70 years on the throne.

Rapturous applause erupted as thousands of royal fans swamped the Union Jack-lined Mall for Trooping the Colour in honour of Her Majesty's 70 years of service.

A whopping 1,200 officers and soldiers from the Household Division are taking part in the Birthday Parade this morning.

But many noticed the rogue horse trotting around during Trooping.

One person wrote on Twitter: "Is there a stray horse in the jubilee parade??"

Another said: "Lol there's a loose horse."

A third added: "Did anyone else just see the horse with no rider atop just then?! Where is the missing rider?! Who caught the horse?!"

The incredible display marks the first event of the Queen's Platinum Jubilee bumper weekend.

Mounted troops from the 1st Battalion and Irish Guards joined hundreds of musicians and 240 horses on Horse Guards Parade.

Prince Charles inspected the soldiers on the Queen's behalf before she appeared on Buckingham Palace balcony for the RAF flypast.

The Queen - wearing a gorgeous powder blue outfit - stood with the Duke of Kent, 86, as they inspected the troops below.

She beamed as she watched the thousands of cheering crowds gather for her birthday celebrations.

Meanwhile, Princess Charlotte, Prince George and Prince Louis all gleamed outside Buckingham Palace and Horse Guards Parade for the Queen's Platinum Jubilee procession.

They rode in a carriage and waved to crowds while processing for the celebrations marking the monarch's 70-year reign began.

The children, dressed in a light blue, navy and white colour scheme, raised their hands to royal supporters who have been lining the streets from the early hours.

The princess also squinted in the sunshine as she looked out on the vast numbers who had gathered to see them.

Cheers erupted from thousands of spectators on The Mall as they caught sight of the trio sitting opposite Kate Middleton and Camilla.

The kids later bowed their heads when the national anthem was played on their arrival into Horse Guards Parade.
