A video has emerged on social media showing a King's Guard screaming at a tourist who put her arm around him while taking a photo outside Buckingham Palace.
The clip, which was shared on TikTok account @thekingsguardsofficial, shows a woman smiling next to a guard dressed in full armour.
But after touching the guard and getting too close to him, the tourist was told off, appearing scared and surprised at his reaction.
In the footage, the guard, holding a large sword, can be seen stamping his foot and turning towards the woman before shouting: "Do not touch the King's Life Guard!"
The video was seen over a million times and divided people's opinion, with some saying that the guard's reaction was justified and one branding him "impolite" and "dramatic".
A person commented: "He's not a show attraction he's there to guard the king. Got a job to do."
Another TikToker wrote: "I mean how many times do people have to be told to stay out of their way, don't treat them like photo props and don't touch their horses.... like."
One more said: "The stomp made me laugh lol."
But some people appeared disappointed at the guard's reaction, with one writing: "Why does he have to yell like that though. Relax guy."
In December last year, another King's Guard was filmed screaming at a tourist as she slapped his horse.
A young woman wearing a white and blue coat was filmed posing for a photo with a soldier who was stationed at Horse Guards Parade in London's Whitehall.
The unidentified woman was filmed standing next to the animal - ready to pose for a photo - as it moved its muzzle closer to her shoulder.
She then seemed to brazenly slap the animal on the nose and grins for the camera, before putting her hands back in her pocket.
The guard screamed: "Stand back!"
In September 2022, a King's Guard told a little girl to "stand clear" as he walked to the outside space at Horse Guards Parade, which prompted her to break into a tearful outburst as she rushed to find her parents.
The interaction could be watched on the video as the child run away after being shouted at.
The guard was part of the senior regiment of the British Army, who have been protecting royal households for hundreds of years.
They are famous for their red outfits and can be spotted standing stoically outside royal landmarks such as Buckingham Palace.
Royal guards are not generally allowed to talk to the public but can occasionally shout a warning in some circumstances, for example when people obstruct them or there is a threat to safety.
