Guardsman collapses during Trooping the Colour ceremony for Queen's official 90th birthday - weeks after another fainted during rehearsals

A soldier in the Household Division collapsed during the Trooping the Colour ceremony at Horse Guards Parade in London today, which were marking the Queen's official 90th birthday celebrations. Such incidents have happened before, including in 2013 and 2011, while a guardsman also collapsed during rehearsals for this event last month. The reason is usually a combination of the temperature - today a balmy 22C - and the heavy uniforms soldiers wear.
