King's Guard screams at tourist after she repeatedly slaps horse

For the millions of tourists who descend on London every year, Buckingham Palace and the Mall are generally top of list of stops along the way.

However, one woman's visit didn't go exactly according to plan when she get a little handsy with one of the royal guard's horses.

At first, nothing seems to be the matter, they take a few pictures and then move away.

As the clip goes on, the pair try and post for their snaps, with the horse nuzzling into the woman wearing a white and blue coat, bumping her a couple of times.

Another guard then races over and the group quickly moves away, with armed police coming over to tell people to leave.

Since the video was shared, it has been viewed countless times, sparking quite the debate.

"People need to remember that they're not an actual tourist attraction," wrote one.

"They have a job and it's real. Winds me up so much."

Another chipped in: "These people are so disrespectful."

The powerful animal then turns its head towards her, forcing the woman to step backwards.

In an attempt to get a bit nearer to the horse, though, she then attempts to grab hold of its reins, much to the annoyance of the guard on its back.

Understandably startled by the order, the woman jumps out of her skin, holding her chest as she backs away.

So, you've been warned.
