The image shows a police officer on horseback in front of Buckingham Palace in London, UK. The officer is wearing a black uniform and a black helmet, and is sitting on a brown horse. He is holding a rifle in his right hand and appears to be leading the parade.

In the background, there is a large crowd of people watching the parade, and a line of soldiers marching in formation. The soldiers are dressed in red and gold uniforms, and they are carrying rifles. The palace itself is white with columns and arches, and there are several statues on top. The sky is overcast, and the overall mood of the image is somber.
