Several British guardsmen faint as Prince William reviews military parade

Several British soldiers were overcome by the heat on Saturday as they turned out in woolen tunics and bearskin hats to salute Prince William.

At least three guardsmen fainted during the military parade known as the Colonel's Review, in which more than 1,400 soldiers of the Household Division and the King's Troop Royal Horse Artillery were reviewed by the heir to the throne, who is honorary Colonel of the Welsh Guards.

The temperature in London on Saturday was due to hit 86 degrees Farenheit.
