The weather was hot, very hot but not as hot as it could be in Lagos Nigeria or Cairo in Egypt.

Temperature was at 26C but this soldier could not withstand it, so he fainted during a parade to mark Queen Elizabeth’s 91st birthday.

The incident almost marred the birthday celebration of Queen Elizabeth.

With the Queen and the rest of the family watching on, the unfortunate soldier took a tumble during the performance at Horse Guards Parade.

He began to wobble before hitting the deck – first on his knees, before tumbling forward head first into the deck.

But the show went on as two officials appeared with a stretcher to collect the collapsed soldier.

He was not to be the only one.

Mirror reports that five Guardsmen were stretchered off Horse Guards Parade in all during the ceremony.

The Queen, 91, marked her official birthday today with the pomp and pageantry of the famous event but also acknowledged the “succession of terrible tragedies” in recent weeks.

Under blue skies and brilliant summer sunshine, the Queen watched the centuries-old military spectacle of might, splendour and precision marching on Horse Guards Parade, Henry VIII’s former jousting yard.

The event is an important day in the armed forces’ calendar where the families and friends of the officers and soldiers on parade, proudly watch the ceremony.
